    The lowtemperature mechanical behavior of molybdenumrhenium

    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 including the role of mechanical twinning.

    Concerning SigmaPhase in MolybdenumRhenium Alloys

    Molybdenum-rhenium alloys containing 40 to 48 Re by weight are commonly used for many high-technology applications. Higher rhenium contents bring the alloys into a two-phase region with the presence of brittle o-phase an intermetallic compound with the approximate composition of Mo 2Re3. Alloys with lower rhenium contents do not possess sufficient low-temperature ductility and high.
