Abstract
Strengthening from defect substructures has been studied in Mo-33Re deformed in tension and by cold rolling, and in shock-loaded molybdenum and Mo-33Re. In cold-rolled and tensile-deformed Mo-33Re, strengthening arises from dislocation-dislocation interactions for smaller strains (less than 0.3), while at larger strains by rolling there is additional strengthening from dislocation cell formation and texture development. In shock-loaded molybdenum, dislocation-dislocation interactions are the primary source of strengthening, while in shock-loaded Mo-33Re dislocations and twin boundaries both contribute to strengthening. The coefficients for dislocation strengthening in both shock-loaded molybdenum and shock-loaded Mo-33Re are consistent with the values for the cold-rolled Mo-33Re and with published values for a wide range of other materials, indicating that the strengthening mechanism is similar for conventional and shock deformation.
