Abstract In situ aluminum alloy matrix composites were processed by Friction Stir Processing. The microstructure and tensile properties of composites after different passes FSP were analyzed. The results show that, in the stir zone, the composites have finer grains and large clustering of particles have been broken up, which leads to a more homogeneous particles distribution. The casting defects produced in preparation process are also eliminated during FSP. The grain size changes from 45 μm to 2 μm. Comparing to 1-pass FSP, after 4-pass FSP, composites have more homogeneous microstructure. Due to the changes of microstructure and the elimination of defects, the tensile properties of stir zone have been significantly improved. The tensile strength of the composite is 1.3 times of base material and the elongation is 8 times of base material.
