18CrMnVB钢奥氏体晶粒长大行为

Austenite Grain Coarsening Behavior of 18CrMnVB Steel

摘要: 研究了6种预先热处理工艺及有效钛含量对18CrMmVB钢奥氏体晶粒长大行为的影响。同时通过与18CrMnB钢比较,分析了Ti和V细化18CrMnVB钢奥氏体晶粒的综合作用机制。

Abstract: The influences of six kinds of conditioning heat treatments and different effective titanium contents on the behavior of austenite grain coarsening were studied. Compared with 18CrMnB steel, the mechanism of combined effect of titanium and vanadium on the refinement of austenite grain of 18CrMnVB steels was analysed.
