Effects of different forging deformation, including amount of 30%, 50%, 70%, on the microstructure and friction and wear behavior of Al3Ti/6063Al composite material microstructure were studied. The results show that Al3Ti in-situ particles were broken and paralleled to the forging direction after deformation. Morphology of matrix grain changed obviously and formed the streamlined texture. Forging also caused a great dislocation in composites. When Amount of forging deformation increases, the friction coefficient decreased and friction coefficient declined under the same load. What’s more 70% forging material had the lowest friction coefficient; the relationship of roughness and deformation had the same function of friction coefficient and deformation., When the deformation amount of material was 30%, the extent of material roughness only can fluctuate in a small range, and change was relatively stable; when the deformation increases, the width and depth of wear scar become wider as well as shallower; abrasiveness and delimitation wear mainly occurred in the process of abrasiveness.
