"Screening of phase transformation kinetics of Ti alloys by high throughput diffusion and mesoscale modeling"
Ti and its alloys, widely used in aerospace, chemical and medical industries, exhibit complex microstructures resulting from multiple alloying elements and complex thermomechanical processes. The microstructure of Ti alloys is further complicated by the formation of metastable phases like ω (hexagonal structure) and β’, leading to alloys whose microstructure is highly sensitive to constituent levels and processing routes. Near β-Ti alloys have been intensively studied in the past using the conventional methods, i.e. one-alloy-at-a-time and one-processing(set)-per alloy. The ScreenPTK project, with a focus on near β-Ti alloys, aims to develop a high throughput diffusion multiple technique for screening of phase transformation kinetics in Ti alloys, which will be used for quantitative mesoscale modelling of the microstructure.
