Abstract
In this present study, fine elemental nickel particles were incorporated into commercially pure magnesium matrix using blend-press-sinter powder metallurgy technique avoiding ball milling. The nickel reinforcement particles dispersion was reasonably uniform with good matrix-reinforcement interfacial integrity. The small volume fraction of elemental nickel particle reinforcement refined grain morphology and significantly improved the hardness and tensile strength of the magnesium matrix without affecting the yield strength. However, ductility was adversely affected. The reinforcement changed fracture mode of magnesium matrix from pseudo-ductile to brittle mode dominated by nickel particle fracture.
