摘　　要：研究了低温预处理对２６Ｃｒ２Ｎｉ４ＭｏＶ钢组织遗传性的影响，提出了低温细化处理工艺。研究结果表明，６５０℃回火和７７０℃退火，均可通过减少残留奥氏体薄膜数量和使α相再结晶的方式细化奥氏体晶粒。The effect of low temperature pretreatment on structure heredity of steel 26Cr2Ni4MoV was studied It was found that both 650℃ tempering and 770℃ annealing can refine coarse austenitic grains of the steel by reducing the amount of residual austenite and making α phase recrystallize
