摘　　要：为了探讨18CrMnBHZ钢奥氏体晶粒粗化规律,采用微调铝、钛、氮、硼、铌等合金元素和改变压缩比方法,并测定其在不同温度下的奥氏体晶粒度,以确定合金元素和压缩比对18CrMnBHZ钢奥氏体晶粒粗化温度的影响。压缩比对粗化温度影响很小,合适的合金元素是有益的,而铌的作用最有效。For research the austenite grain coarsening rule of 18CrMnBHZ, we adjust the amount of Al, Ti, N, B, Nb elements, change percent reduction and determine austenite grain size to confirm the effect of them to austenite grain coarsening temperature. Percent reduction hardly changes the coarsening temperature, correctly amount of alloying elements is useful, and the Nb is the best.
