中文摘要	再结晶温度以上,材料内部缺陷损伤与修复的作用效果对塑性变形能力具有重要影响。本文研究了材料内部孔隙性缺陷修复过程中热力学参数变化特性,对比分析了塑性变形过程中缺陷损伤与修复发生、发展等变化规律。温度-应力状态和温度-时间分别是损伤发生和缺陷修复较为重要的影响因素,提出了增强材料塑性变形能力应采用的方法。; The effect of damage and fault healing has the great influence on the plasticity in materials over the recrystallization temperature. In this paper, he thermo-mechanical properties of cavity-type fault healing were studied, the variations of the fault damage and healing were compared and investigated in plastic deformation process. It has discovered that the temperature-stress state and temperature-time were two important influencing factors to damage and healing of fault, respectively. The effective methods of improving the ability of plastic deformation were put forward.
