摘要

In the present study, elemental and titanium particulate reinforced magnesium materials were synthesized using an innovative disintegrated melt deposition technique followed by hot extrusion. Microstructural characterization of the composite samples showed reasonably uniform distribution of titanium particulates in the matrix material, strong interfacial integrity of magnesium matrix with titanium particulates, and the presence of minimal porosity. Physical property characterization revealed that addition of titanium as reinforcement marginally improves the dimensional stability of pure magnesium. Tensile behavior characterization revealed that the presence of titanium reinforcement led to an improvement of 0.2 percent yield strength and ductility while the UTS was adversely affected. An attempt is made in the present study to correlate the effect of titanium as reinforcement and its increasing amounts with the microstructural, physical and tensile properties of magnesium.
