一、填空 1.多晶体金属在塑性变形时,随着晶粒滑移过程的进行,便引起滑移面邻近的晶格歪扭和紊乱,从而形成____;同时,在滑移面上产生许多细小的晶粒碎块,使滑移面凹凸不平,而增大了滑移____,这样就使多晶体金属进一步滑移发生困难,于是便产生加工硬化。 2.再结晶的作用在干改善金属的____,恢复金属的机械性能和物理性能,完全消除了____所引起的不良影响。因此,再结品对锻造生产具有很重要的意义。
First, fill in the blanks 1. Polycrystalline metal in the plastic deformation, with the grain slip process, it will cause the sliding surface near the lattice distortion and disorder, thus forming ____; the same time, the slip surface generated Many small grain fragments, the slip surface uneven, but increased slip ____, so that the further slip of polycrystalline metal difficult, so they produce work hardening. 2. The role of recrystallization in improving the dry metal ____, restore the mechanical and physical properties of the metal, completely eliminate the ____ caused by the adverse effects. Therefore, the re-product forging has a very important significance.
