Abstract

Bulk-type (Ti0.65Fe0.35)100-xGax (x = 0, 2, 4 at.%) ultrafine composites with high strength and plasticity have been prepared. The composites have a hypereutectic microstructure with primary FeTi phase and (β-Ti + FeTi) eutectic matrix. The composites exhibit high fracture strength of 2290-2766 MPa and large plasticity of 4.8-6.5% under compression. Refinement of eutectic structure and control of relative areal fraction of the constituent phases are the crucial factors in determining the mechanical properties.
