“…After quenching from the β-region within alloy there is formation of a structure with a developed network of grain and sub-grain boundaries (see Fig. 8b) [25]. It is noted that a similar structure undergoes breakdown significantly more rapidly during subsequent isothermal exposure.…”

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.

“…The reason for this phenomenon is completely different; in the XRD spectrum, the peaks for the isothermal ωphase disappeared, while the intensity of the α-phase peaks increased, which indicated an intensive process of β metastable + ω → α decomposition. The dispersion of α-phase precipitates at these temperatures and via such a reaction/mechanism is very high, which ensures strengthening of the β-matrix, and thus an increase in the hardness of the titanium βalloys [6,7,11,13].…”

The ability to obtain a new cost-efficient titanium β-metastable alloy Ti-1.5 (%wt.)Al-1Fe-7.2Cr using conventional cast and wrought technological approaches is investigated. The microstructure and phase composition are characterized in the as-cast, hot-deformed and aged states. The aging behaviour of the state water-quenched from the temperature of single-phase β-field alloy is studied by exposure at 673 K and 773 K, and compared with previously obtained data for the Ti-11V-7Cr-4Al alloy. The mechanical properties are determined by tensile testing of the as-deformed, annealed at the temperature of the two-phase α + β-field, and strengthened by STA treatment (solid solution treatment, water quenching and aging) states. As confirmed, under all the test conditions proposed, the new alloy has an attractive balance of high strength and ductility, which are competitive with those for other titanium alloys of the same metastable β-type.
