Abstract

The effect of the stability of β-phase (of the value of Mo_eq), of the thermal martensite, and of the rate of deformation on the triggering stress of martensitic transformation in alloy Ti – 10% V – 2% Fe – 3% Al is investigated. It is shown that the triggering stress increases with growth of Mo_eq in the presence of thermal martensite and with growth in the deformation rate from 10 ^{– 4} to 10 ^{– 1} sec ^{– 1}.
