Abstract

Bulk (Ti0.65Fe0.35)100−xSnx (x = 0, 2.5, 5 at.%) ultrafine composites with high strength and plasticity have been prepared. All composites have a hypereutectic microstructure with primary FeTi or/and Ti3Sn phases and a (β-Ti + FeTi) eutectic matrix. The ultrafine composites exhibit a high fracture strength of ∼2350–2650 MPa and a large plasticity of ∼7.4–12.5% under compression. The structure of the phases, their refinement and volume fraction are the crucial factors determining the mechanical properties.
