Notes:
The wear resistance, microstructures, worn surface morphology, TiAl3 phases, eutectic Siparticles and the high density of dislocations of the Al-Si-Ti piston alloys have been studied by meansof SEM and TEM. The electrolytic low-titanium aluminium alloys were used to make the Al-Si-Tipistons alloy, the experiment results showed that the wear resistance of the Al-Si-Ti alloy was 1.49times of that of the Al-Si alloy, and the wear mechanism was mainly plastic deformation wear. Therelationship between wear resistances and the yield strength of the Al-Si-Ti piston alloys wereestablished, and the wear mechanism investigated by mean of plastic-elasticity theory. When Ticontent is reached to 0.12%, the yield strength of the Al-Si-Ti piston alloy increased from 255 Mpa to358 Mpa
