摘要

摘要: 借助热模拟试验机分别研究了变形温度为800℃、850℃、900℃、950℃、1 000℃，变形速率为10 s^-1、1 s^-1、 0.1 s^-1、 0.01 s^-1条件下CuNi30Mn1Fe的高温热压缩试验。基于加工硬化率方法，分析了CuNi30Mn1Fe在热压缩变形过程中的动态再结晶行为，并求得发生动态再结晶时所对应的临界应变值。结果表明：CuNi30Mn1Fe在热压缩变形时伴随着动态回复与再结晶的发生；临界应变随着温度的增加而减小，随着应变速率的增加而增加；再结晶峰值应变ε_p和临界应变ε_c的线性关系方程为ε_c=-1.03ε_p+1.36。

Abstract: Thermal simulated test machine was adopted to carry out the hot compression test on CuNi30 Mn1 Fe under different compression temperatures of 800 ℃, 850 ℃, 900 ℃, 950 ℃ and 1 000 ℃ respectively and different deformation rates of 10 s^-1, 1 s^-1, 0.1 s^-1 and 0.01 s^-1. Based on the work-hardening rates of materials, dynamic recrystallization(DRX) behavior of CuNi30 Mn1 Fe was analyzed and the the critical strain of DRX was obtained. The results showed that dynamic recovery and dynamic recrystallization occured during the compression test, that the critical strain of DRX decreased with the increasing of temperature and increased with the increasing of strain rate and that the critical strain ε_c and the peak strain ε_p had the relation of ε_c=-1.03ε_p+1.36.
