Title: MECHANICAL PROPERTIES OF URANIUM PLATE

Abstract

Hot-rolled uranium plate exhibited a pronounced directionality in mechanical properties which was reduced but not eliminated by beta transformation. Results of tensile, bend, impact and hardness tests made at room temperature are summarized for both hotrolled and beta-transfomned uranium plate. Significant differences in mechanical properties existed between ten lots of uranium plate processed under similar conditions. Composition and processing data were inadequate to assign causes for the variations. (auth)

  • 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 bymore » cold rolling were annealed out by the hot-pressing operation. (auth)« less
  • The effect of nickel, molybdenum, iron, and oxygen variables were determined on the mechanical and corrosion properties of Ti-Code 12 within the ASTM specification range for Grade 12 titanium. Properties considered for welded and unwelded 0.25 in. (6.35 mm) plate and 0.070 in. (1.78 mm) simulated strip products included strength, ductility, slow bend and impact fracture toughness, bend ductility, general corrosion, and crevice corrosion resistance. The relative influence of these compositional variables on each specific property was evaluated by means of multiple linear regression analysis. Optimized composition ranges for plate and sheet Ti-Code 12 products, produced by a simulated unidirectionalmore » mill process, were derived from these results based on several assumed sets of property requirements. 20 references, 52 figures, 15 tables.« less
  • In an effort to determine and subsequently optimize mechanical and corrosion properties of the TI-CODE 12 alloy for DHLW container application, a two-stage study was conducted. Stage I was directed toward evaluation of the effect of compositional variations, within ASTM specification limits, on specific mechanical and corrosion properties of TI-CODE 12. Compositional variables investigated were weight percent molybdenum, nickel, oxygen, and iron. Compositional ranges of TI-CODE 12 were identified which correspond to select combinations of desirable properties. Stage II program objectives include evaluation of five distinct thermomechanical processes with respect to TI-CODE 12 0.25 inch (6.35mm) plate and 0.070 inchmore » (1.78mm) sheet corrosion and mechanical propreties, with subsequent selection of a process route which achieves optimum properties. In addition to addressing effects of intermediate recrystallization and cross-rolling steps for reduction of property directionality, the influence of final product anneal is examined. In particular, the influence of a conventional mill anneal at 1450{sup 0}F (788{sup 0}C) is compared to that of the sub-eutectoid 1250{sup 0}F (677{sup 0}C) annual which is known to facilitate precipitation of nickel-rich intermetallic compound in TI-CODE 12. sup (18,19,20). Specific alloy properties considered include tensile strength and ductility, bend ductility, slow strain rate fracture toughness, creep strength, and general and crevice corrosion resistance. 24 refs., 25 figs., 24 tabs.« less
  • The Charpy-V (C{sub V}) notch ductility and tension test properties of three reactor pressure vessel (RPV) steel materials were determined for the 288{degree}C (550{degree}F) irradiated (I), 288{degree}C (550{degree}F) irradiated + 454{degree}C (850{degree}F)-168 h postirradiation annealed (IA), and 288{degree}C (550{degree}F) reirradiated (IAR) conditions. Total fluences of the I condition and the IAR condition were, respectively, 3.33 {times} 10{sup 19} n/cm{sup 2} and 4.18 {times} 10{sup 19} n/cm{sup 2}, E > 1 MeV. The irradiation portion of the IAR condition represents an incremental fluence increase of 1. 05 {times} 10{sup 19} n/cm{sup 2}, E > 1 MeV, over the I-condition fluence. Themore » materials (specimens) were supplied by the Yankee Atomic Electric Company and represented high and low nickel content plates and a high nickel, high copper content weld deposit prototypical of the Yankee-Rowe reactor vessel. The promise of the IAR method for extending the fluence tolerance of radiation-sensitive steels and welds is clearly shown by the results. The annealing treatment produced full C{sub V} upper shelf recovery and full or nearly full recovery in the C{sub V} 41 J (30 ft-lb) transition temperature. The C{sub V} transition temperature increases produced by the reirradiation exposure were 22% to 43% of the increase produced by the first cycle irradiation exposure. A somewhat greater radiation embrittlement sensitivity and a somewhat greater reirradiation embrittlement sensitivity was exhibited by the low nickel content plate than the high nickel content plate. Its high phosphorus content is believed to be responsible. The IAR-condition properties of the surface vs. interior regions of the low nickel content plate are also compared.« less
