The influence of subtransus solution heat treatment on the alpha phase morphology in alpha-beta processed Ti-15Mo-xO was investigated using back-scattered electron microscopy and quantitative image analysis. Initially the alloys examined contained triple point, grain boundary and secondary alpha. Increasing solution treatment above 977K resulted in resolution of secondary alpha, thickening/lengthening, spheroidization and dissolution of grain boundary alpha and coarsening/dissolution of triple point alpha. Measurement of alpha volume fraction, grain boundary/triple point alpha size and grain boundary alpha contiguity allowed selection of alpha-beta solution temperature and time possessing minimum triple point alpha size and grain boundary continuity.
