| 中文摘要 | Friction stir processing (FSP) of cast Mg-9Al-1Zn alloy plus subsequent aging produced a defect-free recrystallized fine-grained microstructure with fine beta-Mg(17)Al(12) particles. Compared to the as-cast parent material, the FSP sample exhibited significantly enhanced fatigue properties, with the fatigue strength being increased from similar to 45 to similar to 95 MPa and the fracture mode being changed from quasi-cleavage fracture to dimple fracture. The improvement was attributed to refinement of grains, elimination of porosities and coarse beta networks, and precipitation of fine beta particles. (C) 2009 Acta Materialia Inc.
