TLDR
In this article, the phase transformation accompanied by diffusion can be induced by application of stress of the order of 100 MPa. This new type of stress-induced phase transformation can decrease the β transus temperature by more than 100 K. The phase equilibrium under stressed condition was calculated by increasing the Gibbs energy of the α phase by 500 J/mol relative to that of the β phase.About:

An Overview of the Thermomechanical Processing of α/β Titanium Alloys: Current Status and Future Research Opportunities
TL;DR: In this paper, a review of the principles underlying thermomechanical processing of α/β titanium alloys is presented, focusing on the formulation of constitutive descriptions for plastic flow under hot working conditions, the evolution of microstructure, the occurrence of defects, and novel/emerging TMP techniques.

Thermomechanical characterization of β-stabilized Ti–45Al–7Nb–0.4W–0.15B alloy
TL;DR: In this article, the deformation and recrystallization occurred preferentially in the grain boundary β phases because its good high temperature deformability enhances grain boundary sliding and migration, and thus improves the workability.

SGTE data for pure elements
TL;DR: In this article, the authors present the data for the condensed phases of 78 elements as currently used by SGTE (Scientific Group Thermodata Europe) as a sound basis for the critical assessment of thermodynamic data, thereby, perhaps, limiting unnecessary duplication of effort.
