摘要
低碳高强度钢25Si2Mn2CrNiMoV在450℃回火状态下产生回火马氏体脆性.本文重点研究了这种钢回火马氏体脆化与钢的组织结构间的关系,提出了碳化物——残余奥氏体——杂质元素交互作用引起回火马氏体脆化的简单模型.
The relationship between microstructure and temper martensite embnttlement (TME) in a low carbon high strength steel is studied in this paper.With a view to explaining formation of TME, a simple model is given which suggests that the interaction among cementite,austenite and impurity leads to temper martensite embrittlment.
