Production of Mg-3Al Based Composites Reinforced with Ti6Al4V Particles

Stir casting is one of the simple, flexible and the cost effective methods for fabricating of metal matrix composites reinforced with particles. In this study, 5%, 10%, 15 vol.% Ti6Al4V particles were added into the Mg-3Al melt during stirring. The tensile strength of Mg-3Al alloy was between 150-190 MPa and 5 vol.% Ti6Al4V / Mg-3Al alloy was equal. However, increasing the particle volume of Ti6Al4V powders to 10 vol.% and 15 vol.% decreased the ultimate tensile strength of composites to 140-170 MPa and 90-110 MPa, respectively. On the other hand, the hardness of reinforced composite was increased for each volume.
