EFFECT OF HOT PRESS CLADDING ON MECHANICAL PROPERTIES AND MICROSTRUCTURE OF URANIUM PLATE
Hot-press cladding did not significantly change the mechanical properties or microstructure of beta-treated or as-rolled metal. The principal effect of cold rolling the beta-treated plate to a 5% reduction in cross- sectional area was an increase in yield strength (from 40,000 to 60,000 psi) with a corresponding decrease in ductility. Hot-press cladding largely annealed out these effects. The hot-press cladding induced partial recrystallization of the 5% cold-rolled metal. The recrystallization resulted in grains of reduced size in the case of the beta-treated, coldrolled metal, and of increased size in the case of the asrolled, cold-rolled metal. Deformation twins caused by cold rolling were annealed out by the hot-pressing operation. (auth)
