Phase transfonnations in beta Ti-13Cr with and without carbon have been studied by scanning electron microscopy and transmission electron microscopy and compared with those found in Ti-15-3 with and without carbon. This research focuses predominantly on the decomposition of meta-stable beta phase after quenching and during ageing. The omega phase is formed prior to the alpha phase below 500°C in Ti-13Cr, while alpha phase precipitates directly from beta phase above 500°C, There is no obvious influence of C on the scale or kinetics of omega precipitation although coarsening of omega is accelerated in the C-containing alloy. Nevertheless, no evidence for omega phase has been obtained in Ti-15-3, Two types of alpha precipitates have been observed in Ti-13Cr.
