摘要： This invention relates to non-ferrous metallurgy, namely to the development of titanium alloys, which, due to their advantageous properties, can be used not only for traditional applications, e.g. defense industry, but also for civil applications. The alloy consists of 0.1 to 3.0 Al, 0.3 to 3.0 Fe, 0.1 to 1.0 Cr, 0.05 to 1.0 Ni, 0.02 to 0.3 Si, 0.02 to 0.2 N, 0.05 to 0.5 O, 0.02 to 0.1 C, and balance Ti. A technical result is a competitive titanium alloy with the guaranteed stable predictable properties which is made using low-grade titanium sponge. The result is achieved with the help of alloying elements which consist of impurities as part of low-grade sponge and separately introduced alloy additions. This titanium-base alloy is characterized by the lower costs as compared with the existing commercial alloys, with the alloy composition selected based on the required physical, mechanical and processing properties. 1 claim, 11 tables.

摘要： This invention relates to nonferrous metallurgy, namely to thermomechanical processing of titanium alloys and can be used for manufacturing structural parts and assemblies of high-strength pseudo-²-titanium alloys in aerospace engineering, mainly for landing gear and airframe application. The method for thermomechanical processing of titanium alloy items consisting of, in weight percentages, 4.0 - 6.0 aluminum, 4.5 - 6.0 vanadium, 4.5 - 6.0 molybdenum, 2.0 - 3.6 chromium, 0.2 - 0.5 iron, 2.0 max. zirconium, 0.2 max. oxygen and 0.05 max. nitrogen is proposed. The method consists of multiple heating operations to a temperature that is above or below beta transus temperature (BTT), hot working with the specified strain and cooling. A technical result of this method is manufacture of near-net shape forgings with stable properties having sections with thickness 100 mm and over and length over 6 m with the guaranteed level of the following mechanical properties: 1. Ultimate tensile strength over 1200 MPa with fracture toughness, K 1C , not less than 35MPaˆšm. 2. Fracture toughness, K 1C , over 70 MPaˆšm with ultimate tensile strength not less than 1100 MPa.
