title = "Anomalous strain-rate dependence of ductility in a fully recrystallized 50Mo-50Re alloy at room temperature",
abstract = "Tensile tests were conducted on a fully recrystallized 50Mo-50Re alloy, in the form of sheet of 0.216 mm thick, at different strain rates ranging from 10-6 s-1 to 1 s-1 at room temperature. It was found that the total elongation of the alloy increased significantly with increasing the strain rate. The fracture surface changed from brittle to ductile with increase in strain rate. Plastic deformation was found to occur by both slip and twinning in this alloy. Electron back scatter diffraction measurements revealed non-uniform plastic strain within individual grains, especially in the vicinity of grain boundary triple junctions. The decrease in ductility at low strain rates in this alloy was possibly related to the interaction between dislocations and trace interstitial elements.",
