Abstract

2024 Aluminum alloy with 15Wt% SiC particulate composite was produced by P/M processing. Mechanical alloying (MA) technique was used to mill the blended powder under purified nitrogen. The results of MA processing have been investigated with SEM, EDAX and XRD. The results show that the matrix particle size and crystallize size reduced after MA and homogeneous distribution of SiC_p reinforcement in the matrix could be obtained. The MA processing also results in cold worked structure, contamination due to oxygen, iron and carbon in the matrix.
