Abstract

A Ti-35Fe-30Zr (at.%) alloy was prepared by cold crucible levitation melting, and its microstructure was characterized. Electron microscope observations revealed a microstructure with a bi-modal phase size distribution. One phase was identified as a monoclinic TiFeZr compound with lattice parameters a = 0.895 nm, b = 0.502 nm, c = 0.969 nm, and alpha = 119.4 degrees in C2 (space group). A bcc beta-TiZr phase with lattice parameter a = 0.341 nm coexisted with the monoclinic phase. The mechanisms of phase formation are discussed. (C) 2013 Elsevier Inc. All rights reserved.
