摘要

Abstract

BSTRACTBiocompatibility of HEAs in the TiZrHfNbTa system in which all the constituents are non-toxic and allergy-free was scrutinized systematically

and novel biomechanical materials with a unique combination of low modulus (57 GPa

almost half that of conventional biomedical titanium alloys)

good mechanical biocompatibility and low magnetic susceptibility (1.71 × 10

−6

−1

similar to that of pure Zr) were successfully developed. Moreover

the underlying mechanisms responsible for phase formation and promising properties were explored. This work not only offers a series of novel bio-metallic materials with prominent properties for practical applications

but also shed light on understanding of phase formation and strengthening of HEAs in general.
