Preparation and Mechanical Characterization of Mg Alloy/HAp Composite by Powder Metallurgy.

The present study focuses on the fabrication and mechanical characterization of AZ31/hydroxyapatite (HAp) composites synthesized via powder metallurgy (PM). Powder metallurgy ensures uniform dispersion of HAp within the AZ31 matrix while maximizing material efficiency. To investigate the effect of HAp content on the composite properties, compositions were prepared with HAp weight percentages of 0 wt.%, 1.25 wt.%, 2 wt.%, 2.75 wt.%, and 3.5 wt.%. The surface morphology of the composites was thoroughly examined using scanning electron microscopy (SEM). The mechanical performance of the composites was evaluated through compressive strength and microhardness tests. The incorporation of HAp particles led to an increase in microhardness due to their reinforcement effect. Furthermore, the enhanced compressive strength was attributed to the higher load-bearing capacity provided by the ceramic phase. [ABSTRACT FROM AUTHOR]
