采用搅拌摩擦工艺（FSP）将7075铝合金的晶粒细化到亚微米级（约250 nm）。研究了所得的显微组织特征。原则上，通过运行多个重叠道次，任何期望尺寸的薄板可以被加工成具有相对均匀的微观结构的超细晶粒微观结构（UFG）材料。(C)2004 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Friction stir processing (FSP) was used to refine the grain size in commercial 7075 Al to a sub-micrometer scale (similar to250nm). The resulting microstructural characteristics were studied. In principle, by running multiple overlapping passes, any desired size thin sheet can be processed to an ultrafine grained microstructure (UFG) material with a relatively uniform microstructure.
