22cr--5ni--3mo--n高合金钢高温变形本构模型研究
Keywords: 金属材料,22cr--5ni--3mo--n高合金钢,流变应力曲线,本构方程,峰值应力
Abstract:
？以工业化生产的22cr--5ni--3mo--n高合金钢连铸坯为研究对象,则采用gleeble--3800热模拟试验机完成了应变速率为0.1--50s-1、变形温度为900--1200℃条件下的高温压缩实验,分析其真应力--真应变曲线变化规律;利用实验数据,构建描述金属高温变形过程流变峰值应力的双曲正弦型、指数型和幂型本构方程;并利用所构建方程对峰值应力进行预测,与实测值对比研究不同本构方程预测的准确性及可靠性,从而为准确选定该类高合金钢高温塑性变形的本构方程提供依据。研究表明:双曲正弦本构方程预测22cr--5ni--3mo--n高合金钢峰值应力时,计算值与实测值吻合最好,相关系数r达到0.998,相对误差绝对值的平均值为4.9\%。
