Abstract

Systematic microstructural investigation on a series of (Ti70.5Fe29.5)100-xVx alloys with x = 0, 1, 3, 5 and 7 reveals that addition of V content causes microstructural refinement and formation of ω-phase. By adding small amount of V (1-3 at.%) into the Ti70.5Fe29.5 binary eutectic alloy, both the strength and the plasticity of the alloys are spontaneously improved up to 2000-2200 MPa and ∼3.5%, respectively. However, large amount of V (5-7 at.%) leading to the high volume fraction of the ω-phase results in degradation in both strength and plasticity. These results suggest that the mechanical properties of the Ti-Fe-V ultrafine eutectic alloys are strongly governed by volume fraction of the eutectic matrix and ω-phases.
