Various phase transformation mechanisms and pathways in titanium alloys have been systematically investigated in Hamish group for a long period of time, using both advanced characterization techniques, such as aberration corrected scanning transmission electron microscopy and 3D atom probe tomography, and computational simulation, such as phase field simulation. In this presentation, the focus will be laid on two topics: 1. The exploration of nano-scale instabilities in titanium alloys, including omega phase (athermal omega phase and isothermal omega phase), O’ phase and O” phase; 2. The development of various fine scale alpha microstructures in titanium alloys, including refined alpha microstructure, more-refined alpha microstructure and super-refined alpha microstructure. Novel understanding of phase transformation mechanisms and pathways in titanium alloys, that could be potentially applied to manipulate microstructural evolution and modify mechanical performance of titanium alloys, will be introduced.
