本文研究了Cr_(25)Ni_(20)合金塑性变形过程中的组织变化及其与σ相形成的直接关系。结果表明,再结晶不是促进σ相形成的必要条件。
In this paper, the change of microstructure during the plastic deformation of Cr_ (25) Ni_ (20) alloy and its direct relationship with the formation of σ phase were studied. The results show that recrystallization is not necessary to promote the formation of σ phase.
