Title: Transmission electron microscopy study of the microstructure of a Ti–Fe–Zr alloy

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 α = 119.4° in C2 (space group). A bcc β-TiZr phase with lattice parameter a = 0.341 nm coexisted with the monoclinic phase. The mechanisms of phase formation are discussed. - Highlights: • Monoclinic TiFeZr phase was observed in as-cast Ti–35Fe–30Zr (at.%) alloy. • The space group of monoclinic TiFeZr phase is C2. • The β-TiZr phase formed in as-cast Ti–35Fe–30Zr alloy.
