摘要：

Surfaces of A319 and A356 castings were treated by friction stir processing to reduce porosity and to create more uniform distributions of second-phase particles. Dendritic microstructures were eliminated in stir zones. The ultimate tensile strengths, ductilities, and fatigue lives of both alloys were increased by the friction stir processing.
