Abstract:
The variation of interatomic interaction energy during allotropic transition in titanium is established by analyzing the stress and temperature dependences of durability. This energy is $\approx$ 458 kJ/mol in bodycentered $\beta$-Ti at a temperature of $T>$ 1155 K, which agrees well with the titanium sublimation heat, and $\approx$ 305 kJ/mol in hexagonal close-packed $\alpha$-Ti at $T<$ 1155 K. Literature data confirming the conclusions drawn are discussed.
