Possible phase transformation kinetic pathways from the high temperature β phase to the low temperature (α + β) two-phase Ti alloys were analyzed using the graphical thermodynamic method and the assumption that diffusionless and displacive transformations take place much faster than phase separation which requires long-range diffusion. It is shown that depending on the composition of a β-stabilizing element, many transformation mechanisms are possible, involving competing continuous and discontinuous displacive/diffusional transformations. We discuss the proposed phase transformation sequences employing existing experimental microstructures.
