Abstract
Oxidation rates and effects of oxidation on mechanical properties of several refractory metal alloys were determined under a variety of temperature/pressure conditions. The alloys investigated were V-4Cr-4Ti, V-5Cr-5Ti, Nb-1Zr, Nb-1Zr-0.1 C, Ta-8W-1Re-0.7Hf-0.025C and Mo-46Re. Although none of these alloys form protective surface oxides, oxidation behavior and accompanying effects on mechanical behavior are quite different depending on whether oxidation results in external film formation, dissolution or internal oxidation. Data are presented on oxidation rate, microstructural development and effects on mechanical properties for the various alloys.
