摘要：

The wear resistance mechanisms of a silicon carbide (SiC) paticulate reinforced Al-Li alloy composite at 250 degrees C by a pyramidal indenter have been studied. It is found that the subsurface damages that control the weal-resistance are: generation of dislocations and cracks in the SiC particles, interface debonding between matrix and reinforcements and plastic deformation of the matrix.
