【 摘 要 】

In this paper, The tensile tests of Mg-2Zn-0.7Ce (at. %) alloys before and after deep cooling show that cryogenic treatment can significantly increase the plasticity of the alloy. The plasticity enhancement is mainly due to the plasticity of the W phase particles precipitated in the cryogenic environment. During the deformation process, the formation of twins is promoted, but its growth is inhibited, which promotes the movement of dislocations.
