Materials Research of Tungsten Alloy Expert Changxu Shi Is Widely Used for Fighter Engine

Famous material scientist, academician Changxu Shi won 2010 National Science and Technology Awards on Feb. 14, 2013. His materials research is widely used for fighter engine in China.

Changxu Shi, male, is born in November, 1920 in Xushui County, Hebei Province, and is graduated from National Northwest Institute of Technology in 1945. He gained metallurgy doctorate in Oute Dan University, America in 1952. He was actively involved in the struggle to fight to return back China during the three-years working at Massachusetts Institute of Technology. He returned back China finally in 1955. He wa in office as director for Metal Research Institute of Chinese Academy of Sciences, director for Science Technological Division of Chinese Academy of Science, deputy director for National Natural Science Foundation Committee of Technological Sciences, deputy dean for Chinese Academy of Engineering, etc. Now he is special adviser to National Natural Science Foundation Committee, honorary director of the Metal Research Institute of Chinese Academy of Sciences. In 1980, Changxu Shi was elected as academician of Chinese Academy of Sciences. In 1994, he was elected as academician of Chinese Academy of Engineering.

For many years, Changxu Shi dedicated to materials science research and engineering applications, he is the first one who carries out the research and development of high temperature alloys such as tungsten alloy, molybdenum, titanium, manganese, rare earth materials and new type of alloy steel in China. Tungsten alloy, molybdenum, titanium, manganese, rare earth and other high-temperature alloys are the core material for aero engine. In the sixties of the last century, our fighter engine urgently needs high-performance and high-temperature alloy blades, he led his unit to develop the turbine blade for casting abalone high-temperature alloys, and these superalloy turbine blade casting abalone developed to solve a series of technical problems, so as to make turbine blades of our aero engine into a new level, which is from forging to casting, from solid to hollow, become the second country who developed the key materials technology by itself after the United States. So far, it has been widely used in fighter engine in China. In 1985, he gained the first prize of National Science and Technology Progress. He developed the low segregation alloy technology in metal solidification theory, reduced the alloy solidification segregation through controling trace elements effectively. On this basis, the researchers at the Institute of Metal Research, Chinese Academy of Sciences was researching and developing all types of aircraft engines and large gas turbine directional, single and high-temperature alloys and complex cavity casting technology under his guidance. According to our resources, he also developed several types of alloy steel to save nickel and chromium, solving the time required for Chinese industry.

Changxu Shi set up Metal Corrosion and Protection Institute of Chinese Academy of Sciences, led the establishment of website of National Natural Environmental Corrosion Station, providing a large number of basic data for our materials research and engineering applications. He strongly advocated it is both of importance of research between traditional materials and new materials, basic research and applied research, promoting the sustainable development of our material research. He promoted the development of our fatigue and fracture material and discipline development such as amorphous and nanocrystalline. He proposed that China should vigorously develop magnesium alloy, advocate and participate in Chinese high-strength carbon fiber research and development applications.

Changxu Shi made outstanding contributions to the formulation of national science and technology policy and the setting and development of science and technology institutions. He initiated, participated in and presided the establishment of the Chinese Academy of Engineering; presided the development plan of national materials field for many times. He attached great importance to the society and published work, creating Chinese Materials Research Society and Chinese Biological Material Committee. He was the founder and editor of the five high-level publications: Materials Science and Technology (English version), Progress in Natural Science (Chinese &English version), Metal Learned Journal (Chinese &English version).

Changxu Shi enjoy a high reputation in the international field of materials science, repeatedly served as conference chairman or consultant in international material field. He won 7 prizes of National Science and Technology Award, and gained Practical Material Innovation Award issued by International Union of Materials Research in 1998. Due to his achievements in materials field, the U.S. Minerals, Metals and Materials Society (TMS) awarded him the title of Honorary Member.

Changxu Shi trained more than 80 masters and doctoral students. Many of them has already become the academic leaders in materials field.
