The omega phase transformation in titanium alloys as an example of displacement controlled reactions
TL;DR: In this paper, the omega phase is shown experimentally to be formed by cooling certain metastable β-Ti alloys to cryogenic temperatures, and the gradual progression from diffuse streaking in the diffraction patterns of the β phase to the sharp ω reflections is interpreted in terms of a displacive type reaction.

Effect of self-accommodation on α/α boundary populations in pure titanium
TL;DR: In this article, a statistical analysis of shape strains produced by the martensitic??? transformation in pure titanium indicates that there are three likely slip systems which could operate to give the complementary shear.
