Influence of Nb on the β→α″ martensitic phase transformation and properties of the newly designed Ti-Fe-Nb alloys.
TL;DR: Ti-7Fe-11Nb possesses the lowest Young's modulus (84 GPa) and the highest deformability among the designed alloys due to the single β phase microstructure, which renders it more desirable than commonly used CP-Ti and Ti-6Al-4V materials and makes it a promising candidate for biomedical application.

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.
