Variability of Hardening Phase Morphology and Topology in Pseudo-β-Titanium Alloys Quenched for β-Structure

Questions of structure formation for “self-hardening” metastable pseudo-β-titanium alloys after deformation and heat treatment are considered. Information is provided for variation of the phase composition in various alloys of this group. Questions of morphology variability and topology of α-phase particles, i.e., the main hardening phase in “self-hardening” metastable β-titanium alloys, as well as the relationship of structural parameters with chemical composition and versions of thermomechanical treatment are considered in detail. The article discusses some of the latest advances in formation of different secondary α-phase morphology and topology, as well as estimates of prospects for further development in this area of research.
