摘要

Abstract

This study investigates the evolutions of microstructure and performance of TiNbZrTaHf-based alloys from equiatomic high-entropy alloys to Ti-rich dilute alloys. A novel biocompatible alloy

12.5

was developed with a high yield strength of 839 ± 12 MPa

low modulus of 61.5 GPa

low magnetic susceptibility of ∼1.99 × 10

−6

−1

and unprecedented tensile plasticity of 28.7 ± 2.2%. The study discusses the underlying mechanisms responsible for these superior performances

attributing the exceptional plasticity to the activation of cross-slip dislocations

enhanced dynamic recovery and high resistance to crack propagation. The findings provide new insights into the development of biomedical titanium alloys.
