| 摘要 | The invention relates to the field of non-ferrous metallurgy, and more particularly to the creation of titanium alloys which, by virtue of their properties, are economical to use not only in traditional, particularly military, fields, but also in civilian fields of industry. The alloy contains 0.1-3.0 Al, 0.3-3.0 Fe, 0.1-1.0 Cr, 0.05-1.0 Ni, 0.02-0.3 Si, 0.02-0.2 N, 0.05-0.5 О, 0.02-0.1 C, and the remainder Ti. The technical result is the production of a commercially viable titanium alloy with guaranteed stable, predictable properties which is manufactured using low-grade titanium sponge. This result is achieved in that the alloying elements used include impurity elements contained in the low-grade sponge, as well as alloying additives separately added to the charge. The titanium-based alloy has a lower price compared to existing commercial alloys and, furthermore, the composition of the alloy is selected in accordance with a prescribed level of physical and mechanical properties and fabrication characteristics. | ||||||
