Abstract
The present work, reviews the mechanical and microstructural analyses, of copper and silicon carbide reinforced recycled aluminium matrix (Alumix 431) composites manufactured by sinter+forging technique. Static compression, impact tests and also scratch damage tests were carried out. Detail analyses of Scanning Electron Microscopy (SEM) supported by XRD, thermal and electrical conductivity measurements have been carried out on the specimens before and after the tests.
The results exposed that, the composites have homogeneous structure without porosity and very homogeneous distribution of fine silicon carbide (SiC) particles. The failure damage in composites occurs in both matrix and particles implying good chemical bonding diffusion between matrix and particles. This composite will be applied on the pieces with high thermal conductivity and high surface damage resistant.
