大量的实验结果表明并非所有面心立方纯金属都会在疲劳后形成典型的驻留滑移带(PSB)梯状结构.规则位错组态的形成,特别是PSB梯结构的形成遵循位错聚集与演化的统一准则.基于这一准则,本文提出了以层错能为基础的简单判据,用以解释不同面心立方纯金属中规则PSB梯结构的形成与否. A large number of experimental results show that not all face-centered cubic pure metals will form typical PSB ladder structures after fatigue.The formation of regular dislocation configuration, especially the formation of PSB ladder structure, follows the dislocation aggregation Based on this criterion, a simple criterion based on fault stacking energy is proposed to explain the formation of regular PSB ladder structure in different face-centered cubic pure metals.
