基于弹塑性力学理论，分析了颗粒增强金属基复合材料在降温及升温循环过程中的热错配应力结果表明，降温期间复合材料基体发生了热错配塑性应变，升温期间则经历卸载过程；在升温期间存在一特定温度，此温度复合材料基体平均错配应力为零．在零应力温度下，热错配应力分布不均匀程度有所减小．零应力温度受复合材料冷却温度的影响，利用低温处理方法可以调整复合材料的零应力温度。
Based on the theory of elasto-plasticity, the thermal mismatch stress of particle reinforced metal matrix composites during cooling and heating cycles was analyzed. The results show that the hot-stalled plastic deformation occurs in the composite matrix and the unloading process during the heating process. There is a certain temperature during the heating temperature, the average temperature at which the composite matrix mismatch stress is zero. At zero stress temperature, the thermal mismatch stress distribution is reduced to some extent. The zero-stress temperature is affected by the cooling temperature of the composite material, and the zero-stress temperature of the composite material can be adjusted by using the low-temperature processing method.
