摘　　要：搅拌摩擦焊发展起来的搅拌摩擦加工(FSP)技术因具有优异的微观组织、不产生的界面反应等优点在颗粒增强铝基复合材料的制备方面得到广泛研究。首先综述了影响搅拌摩擦加工的工艺参数,包括旋转速度、移动速度、下压量以及搅拌道次。这些参数影响搅拌时的热输入,同时热输入会改变复合材料的塑性流动,从而影响复合材料的结构和力学性能。然后重点讨论了搅拌摩擦加工铝基复合材料的工艺方法,通过开孔或开槽法添加强化颗粒的直接加工工艺存在着颗粒团聚的问题,严重影响材料的力学性能,而搅拌摩擦加工作为二次成形工艺间接加工复合材料可以有效提高复合材料力学性能。最后提出目前搅拌摩擦加工工艺在颗粒增强铝基复合材料的制备与发展方面存在的问题以及发展趋势。The friction stir processing(FSP)technology developed from friction stir welding has been widely studied in the preparation of particle-reinforced aluminum matrix composites due to its excellent microstructure,no interfacial reaction and so on.Firstly,we summarized the process parameters which affect friction stir machining,including rotation speed,moving speed,plunge depth and stirring pass.These parameters affected the heat input during stirring,which altered the plastic flow of the composite at the same time,thereby it affected the structural and mechanical properties of the composite.Subsequently,it was discussed that the process method of friction stir processing aluminum matrix composites,and the problem of particle agglomeration in the direct processing process of adding reinforced particles by opening or grooving method seriously affected the mechanical properties of the material,and friction stir processing as a secondary forming process could effectively improve the mechanical properties of the composite material.Finally,it was proposed that the existed problems and development trends of the current friction stir processing technology in the preparation and development of particle-reinforced aluminum matrix composites.
