Conclusions
-
1.
Raising the heating temperature and the cooling rate leads to an increase in the structural instability of alloy VT16 and has a considerable effect on the mechanical properties and phase composition.
-
2.
The lowest value of the yield strength after quenching from different temperatures corresponds to the largest amount of β phase. At first the yield strength decreases sharply with increasing quenching temperatures, coinciding with the formation of α″ phase.
-
3.
The increase in strength of samples quenched and annealed with heating to 750–900°C is identical. For annealed samples it is somewhat lower at small degrees of deformation, and for quenched samples at large degrees of deformation. In this case the ductility (ψ and δ5) of the quenched samples is somewhat higher than for the annealed samples.
