摘要

利用Gleeble-1500D热模拟试验机

采用等温压缩试验

研究了Cu-Fe-P-Zn-Sn-Mg合金在变形温度为750

50℃、应变速率为0.01

0s-1条件下的流变应力的变化规律

测定了其真应力-应变曲线

并分析了合金在热压缩过程中的组织演变规律。结果表明

合金的真应力-应变曲线具有典型的动态再结晶特征

其流变应力随变形温度的降低以及应变速率的提高而增大

且变形温度越高、应变速率越小

合金越容易发生动态回复和再结晶。在试验基础上

计算并建立了合金热变形过程中流变应力与变形温度和应变速率之间关系的热压缩高温变形本构方程。

Abstract

The flow stress of Cu-Fe-P-Zn-Sn-Mg alloy and evolution of the microstructure during hot deformation were investigated at 750

50 ℃ and strain rate at 0.01

0 s-1 on Gleeble-1500 Dtest machine.The experimental results show that the true stress-strain curve of the alloy presents the typical characteristics of dynamic recrystallization.The dynamic recrystallization is controlled by both strain rate and deformation temperature.With decreasing in the temperature or increasing in the strain rate

the flow stress is increased

and the dynamic recrystallization easily occurs with increasing in deformation temperature or decreasing in strain rate.On the basis of the above experiments

the hot compression deformation constitutive equation in the process of hot deformation of the alloy was established.
