Characterization of the α ↔ β transformations in a Ti–6Al–2Sn–4Zr–6Mo (wt.%) alloy

A Ti–6Al–2Sn–4Zr–6Mo (wt.%) alloy has been subjected to different thermal treatments of solution and aging leading to different amounts and distribution of untransformed α-phase, β-phase and martensite. In order to study the α-phase transformation, and thus to evaluate its kinetic behaviour, its characteristics and its influence in subsequent transformations, dilatometric analysis tests, metallographic studies, hardness, and conductivity measurements have been performed.
