摘　　要：研究了三种高淬透性钢的组织遗传特性及低温晶粒细化工艺。结果表明，可通过在６５０℃高温回火和７７０℃退火减少残余奥氏体并使α相再结晶，细化奥氏体晶粒。Structure herdeity and low temperature grain refining process of three kinds of steels with high hardenability was studiedIt was found that 650℃ tempering and 770℃ annealing can refine coarse austenitic grains of the steels by reducing the amount of residual austenite and making αphase recrystallize

关 键 词：组织遗传 晶粒细化 针形奥氏体 高淬透性钢
