Niobfreie Vanadiumbasislegierung hoher Zeitstandsfestigkeit

摘要

An alloy contains 0.1-2.8 percent of at least one of the elements titanium, zirconium, and hafnium, traces to 2 percent silicon, traces of 4 percent germanium, balance vanadium, traces of usual metallic impurities which are due to the manufacturing process and, based on the vanadium content, 400-4,000 p.p.m. oxygen, 100-1,500 p.p.m. nitrogen, and 100-1,500 p.p.m. carbon, the total of oxygen, nitrogen, and carbon being not in excess of 5,000 p.p.m.
