摘　　要：研究了Ｎｉ_（５０）Ｔｉ_（５０）单质混合粉末在不同工艺条件下球磨时层状组织的形成与变化，并根据球磨过程中粉末塑性变形模型研究了层片间距与球磨过程中粉末塑性变形的关系。The formation and the variation of the layered structure in mixed powder of NisoTiso under different ball millins conditions have been studied. According to the powder'S plastic deformation model,the relation between the layer thickness and the plastic deformation of the powder in ball milling process has also been investigated.
