Ti–6Al–4V particle reinforced magnesium matrix composite by powder metallurgy

A novel Ti–6Al–4V particle (TCp) reinforced MB15 magnesium matrix composite, TCp/MB15, was fabricated using powder metallurgy route. Microstructural characterization revealed that a uniform distribution of TCp, good interfacial bond between TCp and the matrix, and a smaller grain-size compared to the unreinforced MB15 were achieved in the composite. Mechanical properties investigation showed the ultimate tensile strength, 0.2% yield strength and elastic modulus of MB15 were markedly increased by the addition of TCp, and the strengthening effect of TCp was better than that of SiC particles. The primary aim of this work was to compare the microstructural and mechanical properties of TCp/MB15 with those of MB15 alloy.
