Several Mo- and Ta-base alloys have been selected as candidate materials for space reactor heat transfer applications. The initial phase of this investigation has compared the effects of inert and oxidizing atmospheres on tensile and bend properties of these alloys. Microstructural variables include texture and degree of recrystallization. Results are discussed with implications for future elevated temperature testing.
