摘要

FIELD: metallurgy.;SUBSTANCE: according to first version titanium alloy contains zirconium and hafnium at their summary amount 0.1-5.0 wt %. According to the second version titanium alloy contains zirconium at amount of 0.1-5.0 wt % and niobium not more, than 5.0 wt %, according to the third version titanium alloy contains zirconium and hafnium at their summary amount 0.1-5.0 wt % and niobium not more, than 5.0 wt %. The item is made out of any of described alloys and is produced by means of fabricating an ingot, by its moulding with at least one hot and cold forming operations and by annealing of moulded semi-product in a single α-region.;EFFECT: alloys and items out of them are characterised with superb effect of hydrogen absorption neutralisation.;6 cl, 4 tbl, 21 ex
