Fully consolidated mixtures of Ti and Al-7mass%Mn were prepared via powder extrusion. The extruded mixtures were synthesized into TiAI intermetallics by the reactive sintering method using HIP. Effect of extrusion ratio of the mixtures on microstructures and room temperature tensile properties was investigated. Tensile yield strength, ulitimate tensile strength and elongation were increased with increasing extrusion ratio up to extrusion ratio 295, owing to a refined microstructure and an enhanced diffusion at higher extrusion ratio.
