Abstract Scope |
Near shape forming of magnesium (Mg) alloy powders offers significant opportunity for structural material light weighting. Work to date indicates Mg/Mg alloy powders can be consolidated using conventional press and sinter processing to some extent. While reasonably compressible, densification of Mg/Mg alloy powders using solid and liquid state sintering is challenging. The presence of adsorbed O2 containing compounds and/or absorbed powder particle surface oxide layers most likely impedes solid and liquid state interparticle sintering. Results presented here attempt to analyze and experimentally progress sintering of consolidated Mg/Mg alloy powders. Thermal desorption results are presented qualitatively identifying powder particle adsorbed O2 containing compounds. Additionally, results of the effect of sintering Mg/Mg alloy powders in totally O2 (g) free inert atmospheres are presented. Sintered powder compacts are generally characterized for density, phase development, microstructure, and microstructure composition. Results of this work are intended to enhance the understanding of sintering Mg/Mg alloy powders. |
