Modeling thermodynamics, kinetics, and phase transformation morphology while heat treating titanium alloys

This article summarizes research work on computer modeling of thermodynamics and kinetics of phase transformation behavior in a number of titanium alloys, carried out in collaboration with TIMET UK. The goal is to model the microstructural evolution of the alpha/beta phases as a function of heat treatment and alloy chemistry including five major titanium alloys. The results of the research include time-temperature-transformation and continuous cooling diagrams. Experimental validation, by measurement of the kinetics of growth and dissolution of alpha and other phases, has been conducted.
