Abstract

This study has clearly demonstrated the solution softening phenomenon in Mo-Re alloys that contain 5.8 to 8.2 at. Re. The intrinsic nature of the phenomenon tends to be supported by this work; however, the addition of rhenium to molybdenum appears to cause a redistribution of interstitials that affects the fracture behavior in worked alloys. Much more fundamental research is needed to clearly establish the mechanisms that cause this phenomenon. The fabrication of these alloys seems to be no more difficult than any molybdenum alloys produced commercially today. Even the control of rhenium content in the maximum solution softening range does not appear to be difficult.
