热加工中道次间残余应变率对流动应力的影响

Effect of Residual Strain Rate between Two Passes on Flow Stress during Hot Processing

摘要: 采用恒应变速率凸轮式压缩试验机,测定研究了GCr15、16MnNb钢在两道次变形过程中,热加工道次时间间隔对钢流动应力及道次间软化率的影响规律.

Abstract: Using cam-type compression testing maching of the constant strain rate, interval between two passes affecting regular on flow stress and soften rate For steel GCr15 and 16MnNb is studied when hot precessing.
