This study investigates the mechanical behavior of a high entropy alloy (HEA): Ti5Nb1Ta1Zr1Mo1Sn1 in as-cast, annealed, and further heat-treated states. The microstructural characterization and compositional analysis were done using scanning electron microscope, electron backscattering diffraction, and X-ray diffraction. It was found that microstructure exhibited elemental fluctuation within the body-centered cubic matrix and formation of Sn3Zr5 intermetallic along the grain boundaries. Such microstructure achieved a high UTS of more than 1.7 GPa, a hardness of more than 460 HV and a ductility of about 09-11%. This can be a low-cost and high-performance alloy for biomedical applications.
