文摘

Based on a large number of experimental results available, it is found that not all the fatigued face-centered-cubic (FCC) pure metals can form the classical persistent slip band (PSB)-ladder structure. The formation of the regular dislocation patterns, especially the PSB ladders, follows one unified principle on the dislocation aggregation and evolution. According to the principle, a simple criterion based on stacking fault energy is proposed to judge whether or not the regular PSB ladders in different FCC pure metals can form. 中文摘要 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.
