摘要
以淬火态马氏体钢为对象,观察了淬火态马氏体钢中板条马氏体和孪晶马氏体的明场相和暗场相,并对W相的存在状态进行研究。结果表明,马氏体中较高含量的W相会降低材料的塑性,甚至会发生脆断。马氏体不同的组织形貌与W相和基体的位向有关。
The dark field and light field of lath martensite and twin martensite in quenching state martensite steel were observed, and the W phase in the martensite was studied. The results show that the high content W phase in the martensite reduce the ductility of the steel. The morphology of the martensite is related with the exposure of W phase and matrix.
