Abstract

Temperature and duration parameters of multiphase (α+α2+β)-structure stability in VT6 (Ti–6.25Al–4.1V, % wt.) titanium alloyformed by thermohydrogen treatment (THT) upon 0.8% wt. hydrogen doping are determined. It is revealed that the structure after THT with the subsequent vacuum annealing at 625 and 650°С possesses the maximal thermal stability during isothermal ageing (more than 100 hours at temperatures up to 650°С).
