| The beta to alpha diffusive phase transformation governs much of the microstructures and properties of novel lightweight titanium alloys. Due to the inherent complexity of hexagonal metals and the multicomponent nature of engineering materials, the study of the alloying effects on phase transformations, diffusion and microstructure in Ti alloys is of demanding, however, it is quite often disjunctive. A conceptual diffusion couple, subjected to diffusion annealing followed by thermo-mechanical processing, not only enables rapid screening of phase diagram, diffusion data and properties, but also allows phase transformation kinetics and microstructural change to be extracted simultaneously. In this paper, this high throughput technique, in conjunction with the DICTRA-base modeling, was utilized to explore and elucidate the alloying effects on the beta to alpha phase transformation in the Ti alloys containing Al, Mo, Cr, V and Fe, thus providing the quantitative composition-microstructure-property relationship. | |
