FIELD: metallurgy.
SUBSTANCE: invention refers to production of α-, pseudo α-, α+β-titanium alloys of secondary raw materials with specified strength characteristics mainly for fabrication of sheet work-pieces, items of structure purpose and structure armour and can be used in defence and civil branches of industry. Alloy contains, wt %: Al 0.01-6.5, V 0.01-5.5, Mo 0.05-2.0, Cr 0.01-1.5, Fe 0.1-2.5, Ni 0.01-0.5, Zr 0.01-0.5, Si 0.01-0.25, O ≤0.3, C ≤0.1, N ≤0.07 and Ti - the rest. Charge is composed depending on required value of ultimate strength of alloy. Contents of alloying elements in alloy are determined from calculated values of aluminium and molybdenum strength equivalents.
EFFECT: obtaining specified stable strength and process properties at implementation of wide spectre of titanium wastes.
