Title: METALLURGY DIVISION SEMIANNUAL PROGRESS REPORT FOR PERIOD ENDING APRIL 10, 1954

Abstract

Transformation kinetics studies were started on Ag - Zr alloys. Tensile properties of Th alloys with additions of 2 and 4% Ti and varving C content were determined. The production of U - Al alloys by reduction of UO/sub 2/F/sub 2/ in a cryolite slag was demonstrated. Dynamic corrosion experiments including impact tests on commercial-purity titanium samples exposed to oxygen-preseurized UO/sub 2/SO/sub 4/ periods in excess of 500 hr indicated that no change in impact behavior occurred. Similar tests on Zircaloy 2 gave like results. Corrosion tests on stress relieved stainless steel weld specimens indicated a generally superior corrosion resistance of welds that had been heated to 1000 deg F for 6 hr compared with as-welded specimens. Data on behavior of materials stuitable for bearings and hard facings in molten fluorides are given. Materials tested in contact with liquid lead include alloys such as 25% Mo-75% Ni. 2% Si14% Cr-84% Fe, Hastelloy B, Ti, Co, Be, and 13% Cr-87% Fe. Studies are in progress on the mass transfer characteritics of various structural metals in contact with fused hydroxides. Evaluation of materials for brazing alloys was continued on the Ni-P eutectic along with studies on other brazing alloys such as Ni-Ge,more » and Ni-Cr. Data on the stress rupture of sheet Inconel specimens in molten fluoride salts and argon at 1300 to 1600 deg are presented. A program was initiated to develop and produce stainless steel steel and control-rod components for long-time service in 10-Mw package power reactor plants. Sintered fuelcorp compacts containing 34 wt.% UO/sub 2/, 65.5% stainless steel, and 0.5% B/sub 4/C were prepared and encased in stainless steel at 1225 deg r, thus demonstrating the fabrication feasibility. Petrographic investigations in support of the ANP fuel program continue. In the stady of IV element alloys new phase diagrams are reported for the systems Ag-Zr, InZr, Pb-Zr, and Sb-Zr. Results of new determinations show the alpha yields beta transition at 870 plus or minus 3%. (For preceding period see ORNL-1625.) (J.R.D.)« less
