摘要
对冷拔态Co40NiCrMo合金的微观组织、抗拉伸性能进行了研究。结果表明:经固溶和冷拔处理的Co40NiCrMo合金室温呈面心立方结构;冷拔过程的塑性变形为孪生和滑移,孪生为主要变形机制;孪晶细化和碎化是大变形量冷拔态Co40NiCrMo合金获得良好的综合力学性能的主要原因。
The microstructure and tensile properties of Co40NiCrMo cobalt-base elastic alloy were investigated.The results show that fce structure is the crystal structure of Co40NiCrMo alloy after heat treatment and hard-drawn.The dislocation slip and twinning are the modes of plastic deformation during the hard-drawn.Twinning is the main deformation mode of Co40NiCrMo alloy after hard-drawn when more deformation is made.
