Abstract
The invention relates to the powder metallurgy. A method for producing articles from titanium alloys involves mixing powder of the titanium containing basis with alloying powders of elements, forming alloys with titanium, compacting into the blanks, which shape corresponds to final products, sintering in vacuum at temperatures at which any liquid phase does not form, at that as the basis is used 10-50 wt. % not separated titanium powder with a particle size of less than 500 microns, obtained from the not separated titanium sponge, which contains up to 2.0 wt. % of chlorine and up to 2.0 wt. % of magnesium, and/or 10-90 wt. % of hydrogenated titanium powder, at that this powder is a mixture of two hydrogenated titanium powders A and B, which contain different amounts of hydrogen, in particular: A powder contains 0.2-1.0 wt. % of hydrogen, and B powder contains 2.0-3.9 wt. % of hydrogen and/or up to 90 wt. % of standard titanium powder and 5.0-50 wt. % of ligature or metal are added as alloying powder elements, at that the ratio between the sizes of powders of the basis and powder alloying elements is of 1: (0.01-0.7), compacting the obtained mixture in the blanks is carried out in molds or by the direct powder rolling, or cold isostatic pressing, or injection pressing to the relative density of not less than 60 % under the pressure of 400-960 MPa, then the compacted blanks are heat to 300- and maintained in this temperature range not less than 30 minutes in the hydrogen atmosphere, which is evolved from hydrogenated titanium and sintering of the articles is carried out in β-region of titanium by heating in vacuum to a temperature of 1000-, at which it is maintained at least 30 minutes. The new technology allows to control the chemical purity and properties of the sintered titanium alloys by cost-effective way, as well as to receive from them articles of the complex shape.
