Consolidation of magnesium (Mg) alloyMagnesium alloys (Mg alloys) powders by near shape forming methods offers significant opportunity for structural material light weighting. Experimental results to date indicate that Mg/Mg alloy powders can be consolidated using press and sinter processingPress and sinter processing to some extent. Attaining full density of Mg/Mg alloy powders using solid and liquid phase sinteringLiquid Phase Sintering is difficult apparently due to the presence of surface oxide layersSurface oxide layer impeding interparticle sinteringSintering. In this work, thermodynamic modelingThermodynamic modeling was applied to determine the equilibrium phases formed at varying oxygen (O2) concentrations for pure Mg and several Mg powder alloys. Complimentary sinteringSintering experiments in relatively O2 free inert atmospheres were subsequently performed to investigate densification and interparticle neck formation during sintering. Additionally, all sintered powder compacts were characterized for density, microstructureMicrostructure, phase development, and microstructure composition. Results of this work are intended to increase understanding of solid and liquid state sinteringSinteringof Mg/Mg alloyMagnesium alloys (Mg alloys) powders.
