1On July 7th, 937, Zhou Huijiu still had one year's opportunity to study in the United States at public expense, and two tutors from the University of Illinois and the University of Michigan asked him to continue his doctoral studies.
1in the summer of 1938, he obtained a master's degree in metallurgical engineering from the University of Michigan. During the two summers of studying for a master's degree, Zhou Huijiu took part in the teacher class of Automotive College sponsored by General Motors, and obtained the graduation certificate.
1September, 1938, he was a professor in department of mechanical engineering and Aviation Department of Kunming Branch of National Southwest Associated University, and worked part-time in Tsinghua University Aviation Institute. In order to make some direct contributions to War of Resistance against Japanese Aggression and the cause of saving the country, Zhou Huijiu left the National Southwest Associated University in 194 1 to work in the chariot research institute of a chariot mechanization school in a ravine in western Hunan.
Director 65438-0942, mainly developing auto parts urgently needed for wartime transportation, teaching in the Institute of Mechanized Engineering. Under extremely difficult conditions, the problems of material substitution, hot and cold working, accuracy and so on have been solved one by one, which has made great contributions to the cultivation of vehicle engineering professionals.
65438-0945, Professor, Department of Mechanical Engineering and Aviation, Chongqing University and Central University.
1945- 1947, professor of department of mechanical engineering, Chongqing University and Central University.
1946 returned to Nanjing with Central University in summer vacation, 1947 transferred to Shanghai Jiaotong University as a professor.
1948, at the invitation of a friend, * * * established a private Wuxi open source machine tool factory (now Wuxi machine tool factory). He was hired as the chief engineer and later served as the factory director. They want to use the state capital of Shen Xin system to build a factory that produces high-quality mechanical products without interference from the Kuomintang. They assembled six overseas students, more than 10 college students and a group of skilled craftsmen. On the eve of the founding of New China, they overcame the difficulties of boss's flight and capital cut-off, and produced textile machinery parts.
1949 Spring, Wuxi and Shanghai were liberated one after another. Hui Zhou waited for a long time with great enthusiasm for the new China, and accepted the processing order from the East China Ministry of Industry at that time. He led the research and development of machinery and equipment that was in short supply and badly needed in China, and produced the first 2m vertical lathe, 12m precision lathe and hemp spinning machine for China, which contributed to the recovery and development of China machinery industry in the early days of the founding of New China.
1952, after promoting the public-private partnership of open source machinery factory, Zhou Huijiu returned to Shanghai Jiaotong University as a professor, participated in the preparation of metallurgical heat treatment specialty, and served as the first director of metal laboratory.
1953 Join the Jiu San Society.
1954 served as the director of the newly established casting teaching and research section. During this period, he stubbornly studied Russian, tried to absorb the advanced contents of Soviet textbooks, combined with the production practice of China factory, opened new courses for two majors, such as metallography, material inspection and testing, casting alloy and quality control of castings, presided over the formulation of the first unified teaching syllabus of metallography and heat treatment in China, and translated the textbook Introduction to Metallurgy of the Soviet Union.
1958, Zhou Huijiu's family moved to Xi 'an in response to the call of the Party and the government to support the northwest construction. He once worked in Xi Jiaotong University, and served as the director of the Department of Mechanical Engineering, the director and deputy director of the Institute of Metal Materials and Strength, and the editorial director of the national textbook of metal materials and heat treatment and thermal processing. He reformed the course of metal mechanical properties, greatly expanded the content, and closely combined the relationship between the composition, microstructure and properties of metal materials with the failure of mechanical parts and its prevention. China's first textbook, Mechanical Properties of Metals (196 1), which was edited by him, has a great influence on domestic education and engineering circles.
1964, Hui Zhou was invited to give lectures in the First Automobile Factory and Luoyang Tractor Factory successively, introducing scientific research achievements and academic viewpoints, and promoting the cooperation between factories and schools. These achievements quickly gained the attention of the country. The State Science and Technology Commission listed the theory of multiple impact resistance as one of the major national scientific achievements in1963 ~1964100.
197 1 year, Zhou huijiu joined the rural team and went to Baoji petroleum machinery factory. He cooperated with workers and technicians to develop a light elevator for oil drilling and production machine with high strength and high hardenability of low carbon martensite steel, and went deep into the drilling site of Dagang Oilfield for testing, which was well received by drilling workers.
Starting from 1976, we cooperated with Baoji Petroleum Machinery Factory to develop the lightweight ring: on the one hand, we used high-strength low-carbon martensitic steel to greatly reduce the weight of the ring, at the same time, we used the fracture mechanics principle to predict the fatigue life of the ring, and further used the surface strengthening technology to extend its service life, so that the lightweight ring was recognized API (api gravity and agreed to use its logo.
1979 was approved to be upgraded to a research institute, and he served as the director.
1980 was elected as an academician of China Academy of Sciences.
/kloc-0 was elected as an academician of China academy of sciences in 1980 (/kloc-0 was renamed China academy of sciences in 1993).
From 1980 to 1984, Zhou Huijiu was the vice president of Xi Jiaotong University.
Zhou Huijiu systematically studied low-carbon martensite and broke through the traditional concept of low-carbon steel material selection. Many people in metallurgical industry are used to thinking that low carbon steel can't be quenched and strengthened except carburization.
Since 1958, Zhou Huijiu has carried out research on strengthening and comprehensive properties of low-carbon martensite, demonstrating that low-carbon martensite with superior properties can be obtained after quenching of low-carbon steel, which has opened up a new way for exerting the strength potential of commonly used low-carbon steel.
After more than 30 years of efforts, low-carbon martensite has been widely used in production. Oil drilling slings, perforating guns, important bolts on automobiles, fishtail bolts connecting tracks, coal chutes and circular chains, transmission shafts of walking tractors, etc. The application of low-carbon martensitic steel has improved the strength level and service life, reduced the weight of parts, saved metal materials and alloy resources, and achieved obvious social and economic benefits.
In theoretical research, Zhou Huijiu has made new discoveries in the microstructure and fine structure of low carbon martensite, free tempering transformation, alloying and hardenability, environmental cracking sensitivity and so on. For example, in low-carbon martensite with different compositions, it is found that there are residual austenite films between lath bundles; In addition, low carbon steel with Ms point (martensite initial transition temperature) higher than 300℃ is accompanied by self-tempering during quenching, thus clarifying the strengthening and toughening mechanism of low carbon martensite.
The project "Research on the Theory and Application of Low-carbon Martensite Strengthening" led by Zhou Huijiu reached the international advanced level and won the first prize of National Science and Technology Progress Award 1987. 65438-0988 At the 6th International Heat Treatment Conference held in the United States, Zhou Huijiu was invited to give a keynote speech on low-carbon martensite at the opening ceremony.
As early as the early 1970s, when fracture mechanics began to spread in China, it attracted Zhou Huijiu's attention. At his initiative, he carried out research on fracture toughness, initiation and propagation of fatigue cracks, fatigue threshold value, low temperature strength and other topics; At the same time, the surface strengthening and residual stress such as shot peening and rolling are studied to overcome the weak links of parts, realize equal strength design and further exert the strength potential of metal materials.
Zhou Huijiu originally wanted to solve the failure problem in mechanical engineering from the perspective of mechanics. After a year of scientific research and practice, he felt that mechanics alone could not solve all the problems, and he had to study the material itself deeply. So he transferred to the Department of Chemical Metallurgy of the University of Michigan, determined to complete another set of courses from scratch and conduct the research on "X-ray observation of grain boundaries".
1999 died in February.
