| 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. | ||||||
