Abstract: Rare metal molybdenum is a strategic basic material with high melting point, high temperature strength, small expansion coefficient, low temperature creep rate and good electrical and thermal conductivity. It is widely used in aerospace, nuclear industry, semiconductor lighting, medical, mechanical processing. In important industrial fields, pure molybdenum metal sheets are used as high-value deep processing end pro-ducts and raw materials for stamping structural parts, and are widely used in high-tech fields. However, since molybdenum itself has a series of processing disadvantages such as high deformation temperature, poor low temperature plasticity, and severe oxidation at high temperature, the process of rolling a molybdenum sheet is difficult, and various defects and problems often occur, such as cracking of the mouth of the head. Layering and edge cracking, etc., severely limit the scope of its application. Therefore, the deformation behavior of high-purity molybdenum metal plastic deformation is studied, and the constitutive equation of high-temperature plastic deformation of pure molybdenum plate is established according to the true stress-strain relationship. The relationship between process parameters, deformation behavior and microstructure evolution can be studied as high performance. The processing and preparation of high-purity molybdenum powder sintered materials provide theoretical and practical basis, thereby enhancing the competitiveness and influence of China’s powder metallurgy molybdenum products in the international arena. In recent years, domestic and foreign scholars have been studying the high temperature deformation behavior and true stress-strain constitutive equation of pure molybdenum by means of thermal simulation test machine. The true stress obtained by thermal simulation compression and tensile test under different temperature and strain rate-strain curve and microstructure diagram, showing the deformation mechanism of high-temperature plastic deformation of pure molybdenum under different conditions: at lower temperature and high strain rate, work hardening plays a major role; at high temperature and low strain rate, the rheological softening phenomenon occurs,the optimum temperature range and strain rate of pure molybdenum thermal processing are obtained. In addition, the true stress obtained by the researchers based on the thermal simulation experiment. The variation law of strain is based on the Arrhenius equation containing the hyperbolic sinusoidal model considering the Zener deformation Z parameter. The constitutive equation between the high temperature plastic flow stress and the deformation temperature and strain rate of pure molybdenum plate is established. According to the constitutive equation, the average relative error between the theoretical and actual values of the flow stress of pure molybdenum slab is small, which indicates that the established constitutive equation can be a theoretical reference for the formulation of pure molybdenum hot forming process. In this paper, the research progress of plastic deformation behavior and constitutive equation of high-purity molybdenum metal at home and abroad in recent years is reviewed. The research progress of high-temperature thermal compression and stretching of powder metallurgy pure molybdenum is introduced. The temperature and strain rate are analyzed. The influence of three degrees of strain on the high temperature plastic deformation behavior of pure molybdenum is established. The constitutive equation of pure molybdenum during high temperature thermal deformation is established, and the future research direction is made constructively.
