Abstract:

Means for inhibiting the rapid oxidation of vanadium alloys were studied. The characteristics of 240 oxide mixtures were studied first to determine those elements whose oxides form refractory oxides with vanadium oxide. Melting points of these mixtures ranged from 1225 to above 2500 F. The most refractory mixtures contained one or more of the following oxides Al2O3, Nb2O3, CrO3, NiO2, TiO2, Y2O3, ZrO2. Twenty-eight of the more refractory oxides were then applied to vanadium sheet but they appeared to offer little protection as coatings. Seventy laboratory-size alloy ingots were cast, processed, and tested for oxidation resistance. Vanadium alloys containing Ti, Al and Ni yielded the most refractory scales and, oxide melting points as high as 1950 F were observed. Some of the more promising compositions could be hot worked by rolling and extruding. Author
