Metastable bcc β phase titanium–molybdenum (Ti–Mo) binary alloys provide attractive mechanical properties compared with other titanium alloys. However, multiple phases formed on quenching from high temperatures in these alloys can be attributed to the competing structural and compositional instabilities. Specifically, the precipitation of the omega (ω), alpha prime (α’) and alpha prime-prime (α’’) phases in the Ti-Mo metastable beta (β) alloys, even in small volumes, can have detrimental effects on the mechanical properties of the alloys. For that reason, understanding of the sizes, morphology, and the spatial distribution of these phases is imperative in designing next generation Ti–Mo based alloys.Therefore, the aims of the proposed study the three dimensional (3D) microstructure (sizes, 3D morphology and distribution of phases).
