Abstract

In this study, three biocompatible high-entropy alloys were synthesized via mechanical alloying and powder metallurgy. The objective was to evaluate the influence of substituting Cr, Fe, and V elements on phase stability, microstructure, and mechanical properties. XRD results revealed a primary BCC structure in all three alloys, with the lowest secondary HCP and intermetallic phases in TiZrNbCrV. This alloy exhibited the highest BCC phase fraction, lowest porosity (3.11%), highest hardness (361 Vickers), highest compressive strength (1055 MPa), and low Young's modulus (24.8 GPa), demonstrating the best mechanical performance.
