Since 1982, Ke Yang has been engaged in applied basic research in the field of "metallic hydrogen" and has achieved many excellent results. During his master's thesis work, he participated in a sub-project of a major national fund project. By using ion probe microanalysis and measurement technology, he successfully obtained the influence law of hydrogen on the interatomic bonding force of B-type titanium alloy, which is one of the few research results in the world that directly verified the hydrogen embrittlement bond theory, and on this basis, he proposed the hydrogen embrittlement mechanism of B-type titanium alloy.
Ke Yang's doctoral thesis is also one of the sub-topics, which is to study the diffusion of hydrogen in metals and the hydrogen trap effect. In view of the fact that the measurement results of diffusion coefficient of hydrogen in pure iron were very scattered in the past, Ke Yang put forward a simple mathematical method to deal with the experimental results of hydrogen diffusion through the analysis and research of a large number of experimental results, so that the diffusion coefficient of hydrogen in metal lattice can be easily obtained accurately with metal samples of general purity. Based on the above research, a mathematical model of metallic hydrogen diffusion with hydrogen trap effect is established. The theoretical simulation of hydrogen diffusion process is in good agreement with the experimental results and can explain some phenomena in the experiment well. The completion of the above work not only enriches the research theory of metal hydrogen embrittlement, but also has important theoretical guiding significance for the study of metal fracture process with hydrogen embrittlement as the main content. As one of the main contents, these works won the second prize in natural science of China Academy of Sciences. Many articles with the above work as the main content were published in Journal of Metallurgy, Scripta Metallurgica and other magazines, which received great attention from colleagues at home and abroad. More than 30 application letters from abroad have been quoted many times by others. Ke Yang's project "Study on Hydrogen Diffusion in Metals and Hydrogen Trap Effect" passed the appraisal organized by Shenyang, Chinese Academy of Sciences.
Since 1989, Dr. Ke Yang, as the main researcher, has participated in two national key projects from the Seventh Five-Year Plan to the Eighth Five-Year Plan, namely, the development of high-strength hydrogen embrittlement resistant steel (alloy) for China's nuclear industry. The research team led by him deeply studied the behavior of hydrogen in Inc907 alloy, and found that the microstructure characteristics of the alloy are an important factor affecting the hydrogen embrittlement sensitivity of the alloy. By changing the size and distribution of precipitation strengthening phases in the alloy structure, the hydrogen embrittlement resistance of the alloy can be significantly improved. The research results laid a theoretical foundation for the successful completion of national key research projects, and passed the joint appraisal of the results hosted by Chinese Academy of Sciences and other three units. Dr. Ke Yang won the first prize of scientific and technological progress of China Academy of Sciences (ranked fifth in the institute), which is a key project of the National Seventh Five-Year Plan.
199 1 year, Dr. Ke Yang, as a visiting scholar of the Royal Society, went to work in the Department of Materials of Oxford University, England, and carried out research on the application of hydrogen in the processing and preparation of metal materials. Among them, the use of hydrogen as a temporary alloying element to prepare titanium-based composites at low temperature, thus effectively reducing the interfacial reaction in the composites, is an international initiative, and has applied for an invention patent in China. The research team led by Dr. Ke Yang used hydrogen to improve the microstructure of titanium aluminum compounds and NdFeB permanent magnet materials, thus effectively improving the material properties and adding new content to the development of material research.
Since 1993, Dr. Ke Yang has participated in the construction and operation of the "National Engineering Research Center for High Performance Homogeneous Alloys" supported by the World Bank loan, actively organized and took charge of a number of application research and development projects with market application background, and successfully developed a number of new technologies and new products that meet the market demand, some of which have achieved certain economic and social benefits. Dr. Ke Yang conducted the research on "New Technology of Seamless Deformation Alloy Precision Pipe", developed a new technology of electromagnetic centrifugal casting with independent intellectual property rights to prepare seamless deformation alloy pipe, and applied for a number of invention patents. Because this technology can significantly reduce the production cost, it has important popularization and application value in the production of high alloy seamless steel pipe. The application of "1 1 project" is in the charge of Dr. Ke Yang.
The pilot base of high-performance hydrogen storage alloy powder for Ni-MH battery built by Dr. Ke Yang from Institute of Metals, Chinese Academy of Sciences has provided world-class products for domestic and foreign markets. Two scientific research projects he participated in at the same time, namely, the development of angular Ni-MH battery (ranked second) and the surface modification of hydrogen storage materials and ultra-high pressure and high purity hydrogen compression device (ranked ninth), passed the results appraisal hosted by Liaoning Provincial Science and Technology Commission and Shenyang Branch of Chinese Academy of Sciences respectively.
At present, the "Major Basic Research on High-performance Pipeline Steel" hosted by Dr. Ke Yang is one of the topics of the national major basic research planning project "Major Basic Research on New Generation Steel Materials". The completion of this project is expected to develop a new generation of high-performance pipeline steel materials for China. Dr. Ke Yang devoted himself to the construction of the National Engineering Research Center, and now the engineering center has entered a virtuous circle stage, with an annual income of nearly 6 million yuan, which laid the foundation for the next leap.
In more than ten years of research and development, Ke Yang has published 56 academic papers, including 20 first authors, and * * * has been cited by others for 53 times (incomplete statistics). He has written more than 10 research reports, applied for patents 12, and translated monographs 1 department.
