Abstract

The microstructure of SiCp-reinforced A356 cast Al metal-matrix composite (MMC) has been investigated by means of transmission electron microscopy and energy-dispersive X-ray analysis. It is found that the MMCcontains beta-SiC, (beta + gamma2)SiC composite, eutectic Si, GP zones of Si sequence, a new J phase and the amorphous phase AlxSi9Ca2. Thegamma2-SiC is lath-like with a triclinic crystal structure having a =0.308 nm, b = 0.305 nm, c = 1.262 nm, alpha = 93.8-degrees, beta = 90.0-degrees, and gamma = 60.0-degrees. The J phase is bulk-like with a C-face-centred orthorhombic crystal structure having a = 0.680 nm, b =1.1 70 nm and c = 0.826 nm.
