Abstract

It was found that a cast Ti-Cu-Ni-Mo-Fe multicomponent alloy exhibited high strength and large elongation. The yield strength (σ_0.2) and plastic elongation of the Ti₅₂Cu₂₃Ni₁₁Fe ₇Mo₇ cast alloy with a diameter of 3 mm are 1250 MPa and 22 %, respectively, under a compressive stress. The main phase of this alloy is a TiNi compound phase with dendrite morphology. The large elongation of the Ti₅₂Cu₂₃Ni₁₁Fe₇Mo₇ cast alloy is attributed to the combined effect of the ductility of a TiNi phase and the large plastic deformation ability of grain-boundary.
