Abstract : The deformation and strengthening of bcc Ti-Mo alloys has been investigated by examining single crystals of Ti-12-1/2 wt.% Mo. A change in deformation mode from twinning to slip occurs when single phase crystals are aged to precipitate omega phase. In the single phase solution treated condition, the crystals deform by (332) <113> twinning. When omega phase is present the crystals deform by <111> slip. The occurrence and formation of alpha phase in Ti-Mo-Al alloys has also been investigated. The relationship between Burgers and non-Burgers alpha phase is discussed with regard to mechanisms of formation and kinetics of the transformation. (Author)
