The wear resistance, microstructures, worn surface morphology, TiAl3 phases, eutectic Si particles and the high density of dislocations of the Al-Si-Ti piston alloys have been studied by means of SEM and TEM. The electrolytic low-titanium aluminium alloys were used to make the Al-Si-Ti pistons alloy, the experiment results showed that the wear resistance of the Al-Si-Ti alloy was 1.49 times of that of the Al-Si alloy, and the wear mechanism was mainly plastic deformation wear. The relationship between wear resistances and the yield strength of the Al-Si-Ti piston alloys were established, and the wear mechanism investigated by mean of plastic-elasticity theory. When Ti content is reached to 0.12%, the yield strength of the Al-Si-Ti piston alloy increased from 255 Mpa to 358 Mpa.
