| Abstract Scope |
The microstructure evolution in the metastable beta titanium alloys can be effectively tuned using a variety of nanostructures such as omega phase, O’ phase, and O’’ phase. Recently, a novel nanostructure, named as incommensurate omega phase, was found in the Ti-Fe based alloys. The incommensurate omega phase was reported to show a different crystal structure compared with the hexagonal structure athermal or isothermal ω phase. In this work, the nanostructures in the Ti-Fe binary alloy were investigated using advanced scanning electron microscopy and transmission electron microscopy. The relationship between the Fe concentration and the nanostructures in Ti-Fe alloy was studied systematically using experiment. The influence of these nanostructures on the precipitation of omega phase and alpha phase during different heat treatment will be introduced.
