Influence of titanium volume fraction on the mechanical properties of Mg–Ti composites

Abstract The influence of titanium volume fraction on the mechanical properties of Mg – Ti composites prepared through a powder metallurgy route has been evaluated. Titanium was added as particles smaller than 25 m and volume fractions ranging from 5 to 15 %. The increase in the volume fraction of titanium particles results in a slight decrease in the maximum strength. In contrast to this, the ductility of all composites was significantly enhanced by titanium additions. The mechanical properties can be explained on the basis of texture changes induced by the presence of titanium particles. The decrease in the basal texture along the extrusion direction as the amount of titanium is progressively increased accounts for the decrease in the maximum strength.
