确定冷态塑性变形时金属及合金的强化规律,对于解决压力加工范围内的许多理论和实际问题都具有极大的意义。借助这些规律可以正确制定冷模锻零件的工艺过程,计算这些过程中的力能参数,解决毛坯纵向稳定性问题,满足产品的使用性能,决定塑性极限以及研究金属及合金的内部结构变化等等。本文对金属及合金在变形比ε=0～2.8范围内(ε=In h_0/h,h_0、h 为试样变形前后的高
Determining the law of strengthening of metals and alloys during cold plastic deformation has great significance for solving many theoretical and practical problems in the range of pressure processing. With these rules, the process of cold forging parts can be established correctly, the force and energy parameters in these processes can be calculated, the problems of longitudinal stability of blank can be solved, the performance of products can be satisfied, the plasticity limit can be determined, the internal structural changes of metals and alloys can be studied, etc. . In this paper, the deformation of the metal and alloy ε = 0 ~ 2.8 range (ε = In h_0 / h, h_0, h is the sample before and after the deformation of high
