- Abstract:采用Gleeble-1500热模拟机研究了W80-Cu20(wt.％)复合材料在变形温度为810~970 ℃和应变速率为0.01~10 s-1条件下真应变达0.69的热变形行为,基于改进动态材料模型(MDMM)和Malas’s准则建立功率耗散图和热加工图,结合微观组织确定出合理热加工参数,并对材料的损伤方式进行分析。结果表明：W80-Cu20复合材料的应力-应变曲线表现出典型的动态再结晶型特征,峰值应力随变形温度的降低和应变速率的增加而增加；确定出W80-Cu20复合材料的合理热加工区域为：840~885℃、0.2~1.42 s-1和885~917℃、0.83~2.05 s-1；W80-Cu20复合材料的损伤方式主要有Cu相撕裂、W-Cu界面分离、W-W界面分离以及W颗粒破碎。
