摘　　要：研究了室温下Mo70-Cu板材不同轧制变形量对其显微组织的变化及不同退火温度对Mo70-Cu板材塑性的影响。结果表明,室温下Mo70-Cu板材的轧制变形机理主要是铜相和钼相的滑移变形及钼的孪生变形;Mo70-Cu板材坯料中间退火温度在1000～1100℃退火1h,板材组织均匀、致密,塑性得到恢复。The microstructure change of Mo70-Cu sheet rolled at room temperature in different deformation degrees and the effect of different annealing temperatures on its plasticity was studied.The results show that the main deformation mechanisms of Mo70-Cu sheet rolled at room temperature are the sliding deformation of Cu and Mo and the twinning deformation of Mo and its plasticity can be recovered with uniform microstructure after annealed at 1000-1100 oC for 1 h.
