搅拌摩擦加工（FSP）是通过产生超细晶组织来改善金属和合金的机械性能的剧烈塑性变形工艺之一。在本研究中，它被用来实现最小晶粒尺寸的铝镁合金。结果表明，由于层错能的影响，随着Mg含量的增加，Al-Mg合金的晶粒尺寸减小。
Friction stir processing (FSP) is one of the severe plastic deformation processes that have been developed to improve the mechanical properties of both metals and alloys by producing an ultrafine-grained structure. In this study, it was used to realize the minimum grain size in Al–Mg alloys. The results indicate that the grain size in Al–Mg alloy decreases with increasing Mg content because of the influence of stacking fault energy in the Al–Mg alloy.
