摘　　要：在许多相关的文献中,都注意到α-钛的不同寻常的三级应变硬化行为。在此文中讨论了三个的变形机制:Hall–Petch效应、Basinski机制以及纹理变化所引起的软化作用。然后结合相关文献报道和其他相应的研究结果 ,来探讨Hall–Petch效应的内在机制及其理论模型。In many related literature,the unusual three stage strain hardening behavior of alpha titanium is noted.In this paper,three deformation mechanisms are discussed:the Hall-Petch effect,the Basinski mechanism and the softening effect caused by the change of texture.Then the internal mechanism and theoretical model of the Hall-Petch effect are discussed in the light of relevant literature and other relevant research results.
