## Description

Abstract: As-cast Ti-20Fe-20Co alloy was found to have a combination of very high strength and ductility due to its bcc Ti plus Ti(FeCo) dual phase microstructures. However, this structure is not stable and formed a large amount of Ti2(FeCo) phase during homogenization, which is brittle and significantly reduces the material’s ductility. Although the high strength and ductility of this ascast material is attractive, the potential of this alloy in large scale industrial applications remains uncertain and requires further research.
