The mold repair and maintenance of A-MAX steel die with crack and wear were carried out by laser welding, and the microstructure, tensile property and fatigue property of the die were analyzed. The results show that there are fine lath martensite and some white ferrite structures distributed along the grain boundary in the weld zone of the high power laser pointer welding joint. The HAZ of the joint is ferrite and pearlite. After laser welding of the mold tensile strength and elongation of the new A-MAX mold 93.95% and 88.92%, and the repair of the fatigue life of the mold has been significantly improved, and the new mold fatigue cycle times in the same order of magnitude.
Mold manufacturing with the rapid development of industrial technology and expanding, in the modern manufacturing industry, especially in the field of precision manufacturing to obtain a wide range of applications, can effectively improve the utilization of materials and extend the service life of the product. With the rapid development of die-casting industry, die-casting molds on the overall mechanical properties and service life of higher demands, and because of the high cost of die-casting molds, molds in the long-term use conditions due to high-speed, high pressure, alternating hot or cold The working environment of the load causes the mold surface or the internal appearance corrosion, the wear or the crack causes the mold performance to drop, may even cause the mold to fail. The manufacture of molds involves the selection of materials, complex precision machining and associated heat treatment systems, which are expensive to manufacture and long in cycle time. Therefore, in order to avoid the mold due to cracks or wear and other forms of failure affecting production, and the use of mold repair welding technology, the technology is a die surface to solve the direct and effective method. Laser welding technology as a high-power density, energy concentration, the loss of welding consumables is small, and easy to automate the efficient high-precision welding, can achieve large penetration depth, low residual stress and deformation of the welding components, so laser pointer repair mold welding technology Because of its low cost, short cycle, good repair effect and become a common mold repair welding technology to overcome the cold welding and welding in the repair of fine mold surface defects.
Test conditions: The object of the study is a cracked engine block die casting mold. The mold material is A-MAX steel. It is refined by vacuum electroslag remelting process. The hardenability is good. The service life is 3-5 times of SKD61 steel. The crack depth is 40% lower than that of SKD61 steel. The steel has excellent resistance to cracking, high temperature toughness, high temperature strength, fire resistance and high temperature strength properties for a variety of large, complex die-casting molds. During the test, acetone or absolute ethanol was used instead of industrial cleaners for surface cleaning prior to welding. Repeated cleaning was necessary to meet the welding requirements because incomplete cleaning or secondary contamination could eventually lead to a significant reduction in repair quality .
Test equipment: laser welding equipment using SLC CNC laser multi-function machine, power 5KW, wavelength 10.6μm, the minimum spot diameter of 0.12mm, welding speed of 1m / min, shielding gas for argon.
Test method: Tensile test was carried out by using HY-932 tensile testing machine. According to GB / T 228-2002 standard, the total length of tensile specimen is 200mm, segment length is 95mm, radius of arc is 20mm, test temperature is Room temperature. The fatigue properties of the joint were tested with QBG-25 high frequency fatigue tester. The fatigue specimen was made according to GB / T 2015111-1994. The stress ratio of cyclic stress was 0.1 and the frequency was 100Hz. In order to reduce the test error, two samples of each parallel test.
Test results and analysis: can be seen from Figure 1, the center of the weld between the two plates in the phase plate. Because the base material is austenite and ferrite, the middle of the weld is fine grain structure, and the fusion zone is columnar. Because burning laser pointer welding has high peak temperature, faster welding speed and cooling rate, The heat affected zone of the laser welding of the -MAX steel mold is very small, but it can be seen that the microstructure of the heat affected zone of the joint in the mold repair is white ferrite and black pearlite structure. As can be seen from Figure 1b, A-MAX steel weld microstructure is relatively small quenching organizations, but also observed a small lath martensite and some along the grain boundary distribution of white ferrite. In addition, there is a small amount of fine precipitates in the welds of the A-MAX steel, which improves the strength of the A-MAX steel molds. Because the energy density of the laser beam is concentrated during the laser welding process, and the welding speed of the 50mw laser pointer is relatively fast, the liquid metal in the joint melting zone will solidify at a faster cooling rate, which is equivalent to a once Rapid hardening process, get the strength, hardness and plasticity of good lath martensite structure.
The left figure shows the results of comparison of the tensile strength and elongation of the new mold. The tensile strength of the new A-MAX mold is 843MPa and the elongation is 9.419%. The tensile strength of the A-MAX mold is 792MPa and the elongation is 8.375%. After the repair, the tensile strength of the mold reaches new A-MAX 93.95% of the mold, the elongation of the new mold also reached 88.92%. It can be seen, after 5mw laser pointer welding repair hot work die welded joints tensile strength and elongation are very close to the new A-MAX mold, with better mechanical properties. The reason for the weld strength at the mold repair site is close to the A-MAX steel base material, because the mold repair site is the highest energy and temperature zone in the laser welding, resulting in the welding zone in the welding direction is greater than the welding temperature Ac3 line temperature, and A-MAX steel quenched and tempered composition was more evenly distributed. So that at high temperature conditions, carbon and other alloying elements can be fully diffused, easy to obtain a uniform composition of austenite organizational structure. In addition, the green laser pointer welding speed is faster, and then the weld zone will melt rapidly at a rapid rate of cooling down, and finally the formation of regularly arranged carbon-lean lath martensite and a small amount of residual ferrite, and by laser welding , The lath martensite structure obtained by welding joint is more fine.
The figure on the right is the results of fatigue tests on two specimens tested on a QBG-25 high-frequency fatigue tester. Sample 1 and Sample 2 are fatigue samples of the restored mold, and Sample 3 and Sample 4 are fatigue samples of the new mold. It can be seen that the number of fatigue cycles of sample 3 is the largest, and the average of two tests is 20619 times. The average number of fatigue cycles of A-MAX mold 1 and sample 2 is 17322 times, 83.69%. It can be seen, the mold is about to scrap the use of laser repair welding after the high-frequency fatigue life is improved, close to the new A-MAX mold, and with the new mold fatigue cycle has been in the same order of magnitude.
The microstructures of HAZ are ferrite and pearlite microstructure, and the microstructures of the joint HAZ are ferrite and microstructures. The tensile strength and elongation of the hot work die were 93.95% and 89.92% of that of the new A-MAX mold, and the mechanical properties of the mold after the repair were close to that of the new A-MAX mold. After 2000mw laser pointer welding repair Thermal die fatigue life of about 83.69% of new mold, with the new mold fatigue cycle has been an order of magnitude.

In the 1970s, a man named Gordon Moore predicted his performance in the semiconductor industry by doubling the chip's performance every 18 months. This prediction over the past 40 years all the way to prove his right, and the transistor density of the chip also followed by doubling, doubling, and then double. For people who are familiar with the chip, high-performance is usually associated with this high fever, with our dependence on electronic products increasing, mobile phones, laser 5000mw,flat panel, notebook computers and other heating problems, not only negative impact on the experience, The manufacturers to design a more beautiful, lightweight new products.
To solve the electronic products, especially micro-electronic devices of the heat, we must first understand the root causes of these heat generated. And the answer may be hidden in the latest paper published by Dr. Liao Linlin. The former Sichuan Province college entrance exam tutor from Professor Chen Gang, this year from the Massachusetts Institute of Technology received a doctorate. His research team accurately measured the interaction between electrons and phonons, the results not only explain the micro-electronic equipment, the causes of fever, but also can be used to further improve the performance of thermoelectric materials.
With the development of semiconductor chips, more and more transistors are stuffed into smaller and smaller spaces. Massachusetts Institute of Technology engineers recently found that mobile phones, laptops and other electronic devices will be hot, the main reason is that electronic and thermal energy to carry the phonon interaction. This interaction was once overlooked by scientists, but the latest research results show that in microelectronic devices, this interaction has a significant impact on heat dissipation, the related research results published in the October 12 of the "Nature Communication ".
In the 1970s, a man named Gordon Moore predicted his performance in the semiconductor industry by doubling the chip's performance every 18 months. This prediction over the past 40 years all the way to prove his right, and the transistor density of the chip also followed by doubling, doubling, and then double. For people who are familiar with the 3000mw laser pointer chip, high-performance is usually associated with this high fever, with our dependence on electronic products increasing, mobile phones, flat panel, notebook computers and other heating problems, not only negative impact on the experience, The manufacturers to design a more beautiful, lightweight new products.
Thermoelectric materials have a very wide range of applications, including thermal detectors and NASA's latest proposed for space exploration equipment, nuclear batteries. The phenomenon of electron scattering by phonons is not new, but has long been neglected by scientists. With the continuous development of semiconductor technology, the concentration of electrons becomes higher and higher, this phenomenon can not be ignored. Scientists must think about how to manipulate the electron-phonon interaction in order to increase the efficiency of the thermoelectric device on the one hand and prevent the microelectronic device from heating up on the other.
Phonon and electronic bumper car games
Whether in 20000mw laser transistors (semiconductor materials, such as silicon) or wire (conductor material, such as copper), the electronic current movement is the main medium. The reason why resistors exist is that the electrons flow through a roadblock - a phonon carrying thermal energy collides with electrons, pushing it out of the current path. For a long time, scientists have been investigating the effects of electron-phonon interactions, but the focus has been on electrons rather than on how the interactions affect phonons. "Scientists rarely study the effects of this interaction on phonons, because they think this effect is not important," Liao Lin said, "but Newton's third law tells us that each force has a reaction force, but we do not know what The reaction will become important. "
Scattering, heat is difficult to coexist
According to Liao and colleagues, when the electron concentration exceeds 1019 electrons per cubic centimeter, the interaction of electrons and phonons in silicon, the most commonly used material in semiconducting materials, can produce a large scattering of phonons. When the electron concentration reaches 1021 per cubic centimeter, the heat dissipation capacity of the material will be reduced by phonon scattering by 50%. "This is a very significant effect, but many people are doubtful," Liao Lin Lin said. This is mainly because in previous experiments with high concentrations of electronic materials, scientists have assumed that the cooling capacity of the decline is not due to electron - phonon interaction, but due to material defects caused. These defects are due to the doping of materials, silicon, for example, phosphorus and boron are commonly used doping atoms, the purpose is to increase the material's electron concentration. Therefore, to verify Liao Linlin's theory, it is necessary to separate the electron-phonon interaction and the influence of defects on heat dissipation capacity. The specific method of implementation is to increase the electron concentration in the material, but not to introduce any defects.
The team developed a technique called three-pulse photoacoustic spectroscopy to optically increase the concentration of electrons in silicon crystal thin films and measure phonon production in the material Of any impact. The technique is an extension of the traditional "two-pulse photoacoustic spectroscopy" in which the scientists accurately control the timing of the two blue laser pointer beams. The first beam produces phonon pulses in the material and the second beam measures the scattering or attenuation of the phonon pulses. Liao Linlin introduced a third laser beam, which can accurately increase the electron concentration in the silicon material without introducing any defects. After the third laser beam is emitted, the measurement results show that the phonon pulse decay time is significantly shortened, which indicates that the electron concentration increases the phonon scattering and inhibits its activity.
The experimental results show that the introduction of the third burning laser pointer can shorten the decay time of the phonon pulse. The larger the laser intensity (the higher the electron concentration), the shorter the decay time of the phonon pulse. The result was a great excitement for Liao Lin's team, which was a good match for their previous calculations. "We can now determine the effect is very obvious, and we confirmed it in the experiment," Liao Lin Lin said, "This is the first can directly detect the electron - phonon interaction on the impact of phonons experiment." Interestingly, The concentration of 1019 electrons per cubic centimeter, than some of the existing transistor is even lower, in other words, the latest discovery of this phenomenon is part of the existing microelectronics fever one of the culprits. "According to our research, this effect will become increasingly important as the size of the circuit gets smaller," says Liao. "We must seriously consider this effect and study how to use or avoid its effects."
In the past 10 years, the global laser system has maintained a 7% annual growth rate, which in 2015 laser materials processing system market reached 11.8 billion US dollars, industrial laser 3.2 billion 3.7 times. In 2005, China's burning laser pointer materials processing system only about 3 billion US dollars of turnover, accounting for only 5% of the global market. In 2011, the domestic market grew to $ 1.8 billion. In 2015, to $ 2.8 billion, accounting for 24% of the global market. Since the 1990s, the United States in the field of industrial manufacturing created a new application of laser systems; since then 20 years, Europe will replace the United States as the industry leader; in 2015, China replaced Europe, the first time to become the largest laser system, the consumer market .
Those who have been concerned about the development of the laser industry should be remembered that Japan was almost the world's largest laser market in the 1980s, but then the market share fell and industrial productivity shifted from Japan to other countries with low labor costs. Of course, we do not want China to happen in the future. At present, the domestic laser material processing market prosperity, established in the domestic large and growing industrial base. As long as China's manufacturing growth rate is higher than other parts of the world, is expected to laser materials processing system demand will be higher than the average growth rate.
Fiber lasers dominate
In 2005, fiber lasers accounted for 37% of the global 20000mw laser materials processing market share, in addition, gas lasers accounted for 37%, high-capacity solid, semiconductor lasers accounted for 26%. The market share of fiber lasers has increased significantly over the past 10 years, from 4 percent in 2005 to 14 percent in 2010, up from 37 percent in 2015, to $ 3.2 billion. Over the past five years, fiber laser processing market has been the average annual growth rate of nearly 30%. Fiber laser in the field of rapid development of materials processing, thanks to the following three aspects: First, the application in the marking, the replacement of solid-state lasers; Second, in metal cutting, replacing the CO2 laser; Low-power laser welding, fiber lasers occupy a large market share. At the same time, the industrial laser market is still a large part of fiber lasers can not be involved, including micro-processing applications, because the fiber laser can not provide the required specific wavelength pulse. There are some ablation and structural processes and micro-lithography processing, a lot of non-metallic materials processing technology, more favored in long-wavelength CO2 lasers.
Fiber lasers market share can continue to grow long
According to market assessment, fiber lasers in the alternative to other lasers on the road will continue to make strides. Now, fiber lasers have dominated the laser marking market, but also in sheet metal cutting and high-power welding, but also significantly better than CO2 lasers. In the high-power laser cutting and welding market, fiber lasers will increasingly compete with disk and diode lasers, not just CO2 lasers. However, it should be emphasized that fiber lasers not only replace the solid-state lasers in the laser marking market, but also promote the low cost of industrial applications of lasers. Fiber lasers for marking have been developed to a low cost of several thousand dollars. In metal cutting, because the fiber laser is low in price, easy assembly, greatly reduces the overall cost of the system.
The use of fiber lasers has only just been realized in the field of laser material manufacturing, and now only plays a small role in replacing other types of lasers. Pulse fiber 500mw laser in the pulse welding and drilling applications more and more successful, and ultra-fast fiber lasers also began to get involved in the field of micro-processing. In view of these market developments and opportunities, the demand for fiber lasers is expected to continue to grow with the growth of the market, but the long-term growth rate may be lower than in the past to a certain extent.

It is reported that researchers have developed light-based communication tool that can achieve a lot of fast transmission of data in a helical path, and then resolve potential bottlenecks with the growing demand for information sharing brought data transmission. The new technology uses a vortex beam running through the helical path, so that the data is encoded as a swirling twist.
Compared to conventional burning laser pointer, the beam shape so that it has greater freedom in terms of data-encoded optical communication, as compared linear laser transmission, which is the amount of information carried by more than ten times higher. Because of the increasingly powerful silicon chips, the size of today's computer has been scaled down to build the required number has twisted beams, usually by high-capacity optical devices.
One possible method is through the use of a light source and a twist of optical angular momentum can be controlled amount of energy in the internal design of the device structure formation.
In order to produce practical applications for lasers swirl, UB researchers will be scaled down to the vortex laser chip compatible with today's computer used computer. They orbital angular momentum (OAM) in a spiral pattern of distribution of the laser, and proved the ring resonator semiconductor 2000mw green laser can produce single-mode laser OAM swirl, OAM mode can precisely define the topological charge.
The research team said, OAM related laser polarization can be further manipulated according to the needs, in order to form a radial polarization vortex. OAM laser use, especially micro-nanometer laser to address the growing demand for information capacity. The research team OAM micro laser can be used in next-generation optical communications integrated optical devices.
Since the wavelength division multiplexing and time division multiplexing technology is increasingly close to the data transmission limit, or micro-200mw green laser applications will increase the information transmission rate of telecommunications and information technology.
Laser technology is one of the four great inventions of the twentieth century and atomic energy, semiconductor and computer par. Thirty years to the laser-based laser technology in China has been rapid development, is now widely used in various fields of industrial production, communications, information processing, medical, military, culture, education and scientific research, and achieved good economic and social benefits to the national economy and social development will play an increasingly important role.
