Taking two metastable β-titanium alloys VT22 (Ti—5 (% wt.) Al—5V—5Mo— 1Fe—1Cr) and Ti—3Al—4.5Fe—7.2Cr as program materials, the influence of β-grain size, phase composition, and strain rate (in the range of 3.20∙10⁻⁵ up to 1.81∙10⁻¹) on alloys’ mechanical behaviour is investigated. The mechanical be...
