Abstract
The wear resistance mechanisms of a silicon carbide (SiC) paticulate r einforced Al-Li alloy composite at 250 degrees C by a pyramidal indent er have been studied. It is found that the subsurface damages that con trol the weal-resistance are: generation of dislocations and cracks in the SiC particles, interface debonding between matrix and reinforceme nts and plastic deformation of the matrix.
