Abstract

The microstructure and interface structure of the particle reinforced6061-Al metal-matrix composites have been studied by optical microscopy, transmission electron microscopy (TEM), high resolution electron microscopy (HREM) and energy dispersive X-ray spectroscopy (EDX). The SiC particles are uniformly distributed in the matrix. The constituent phase observed in the matrix is Al-15(Mn,Fe,Cu)(3)Si-2. It has a BCC structure with lattice parameter a=1.28 nm. The SiC reinforcements are found to contain hexagonal alpha-SiC (including 6H alpha-SiC and 4H alpha-SiC) and cubic beta-SiC. Stacking faults are observed in the SiC particles. SIC reinforcements are well bonded with the matrix. In most cases, the interface between the SiC particles and the matrix is cleanand no reaction product was observed. However, certain amount of oxygen and magnesium elements have been found at the interface. The reaction products at the interface are identified to be MgAl2O4, and MgO. The size of these particles are found to be of several nanometers. (C) 1998 Elsevier Science S.A. All rights reserved.
