摘要: We have recently reported that parallel stacking faults (SFs) can tremendously increase the strength of a magnesium alloy. The strengthening is found to linearly with reciprocal mean SF spacing, d. In this study we analyze dislocation interactions SFs, and then propose physics-based model explain observed relationship between yield SFs spacing. Similar empirical Hall-Petch for grain size, it expected mechanism will hold true variety materials engineered spaced over wide range fault
