摘要

采用等温压缩试验法

测定了新型Al- 10Sn - 4Si合金高温变形过程的真应力—真应变曲线 ;在温度为 10 0～ 40 0℃范围和应变速率为 0 0 0 1～ 1 0s 1范围的变形条件下

研究了该合金的流变应力变化规律 .结果表明

Al- 10Sn - 4Si合金为正应变速率敏感材料

表现出稳态流变特征 :稳态流变阶段

流变应力基本保持不变 ;稳态流变应力随变形速率的增加而增大

随变形温度的升高而降低 .进一步分析表明

这种稳态流变特征与动态回复、动态再结晶及局部晶界粘滞性流动行为有关

受热激活过程控制 .通过回归分析

得出了该合金高温塑性变形时稳态流变应力的半经验方程
