Abstract
AM60B magnesium alloys, with and without dispersed SiC particles, were oxidized between 400 and 550 °C in air. The scales generated consisted primarily of MgO and a small amount of Mg3N2 formed by the outward diffusion of cations (Mg, Al, Mn) and the inward diffusion of anions (N, O). The SiC particles were stable in the AM60B alloy during oxidation and increased its oxidation resistance to a certain extent. However, given the predominance of the non-protective MgO as the main oxide, the SiCp/AM60B composites were inevitably destroyed as oxidation progressed.
