Abstract. Various Mo–Re alloys are attractive candidates for use as fuel cladding and core structural materials in spacecraft reactor applications. Molybdenum alloys with rhenium contents of 41–47.5% (wt%), in particular, have good creep resistance and ductility in both base metal and weldments. However, irradiation-induced changes …
The positive effects of rhenium additions on the mechanical behavior of group VI-A refractory metals have been known for decades. In particular, rhenium enhances high-temperature strength and creep resistance as well as low-temperature ductility. This article outlines the low-temperature mechanical behavior of molybdenum-rhenium, …
