Review of Ductilizing of Group VIA Elements by Rhenium and Other Solutes

Abstract

The ductility of Group VIA alloys containing rhenium and other solutes from Groups VIIA and VIIIA was reviewed. The rhenium ductilizing effect, found in Group VIA alloys containing 25 to 35 at. % Re, is promoted by other solutes from Group VIIA and the early portions of Group VIIIA. The hardness minimums and lowered ductile-brittle transition temperatures observed in dilute Mo-Re and W-Re alloys are attributed to solution softening. This phenomenon occurs at low temperatures and is common to many dilute body-centered-cubic alloys containing substitutional solutes.
