HIGH ENTROPY ALLOY FOR BIOIMPLANT APPLICATIONS

Abstract

A non-equiatomic high entropy alloy (HEA) includes titanium in an amount of 33 to 37 atomic percent, zirconium in an amount of 33 to 37 atomic percent, niobium in an amount of 18 to 22 atomic percent, tantalum in an amount of 3 to 7 atomic percent, and silver in an amount of 3 to 7 atomic percent, wherein atomic percent is based on the total atom count of the HEA. The elements titanium, zirconium, niobium, tantalum, and silver are randomly distributed within the HEA. A method of preparation thereof and its use thereof as a bioimplant with improved corrosion resistance, anti-bacterial properties, and reduced elastic modulus.
