利用MMS-300热力模拟试验机进行了GCr15轴承钢单道次压缩试验,采用Poliak和Jonas提出的基于应变硬化率曲线的分析方法,确定了GCr15轴承钢的动态再结晶临界应变εc和峰值应变εp。
The single pass compression test of GCr15 bearing steel was carried out by MMS-300 thermal simulation test machine. Based on the analysis method of strain hardening rate curves proposed by Poliak and Jonas, the dynamic recrystallization critical strain εc and peak strain εp of GCr15 bearing steel were determined .
