FUNDAMENTAL AND APPLIED RESEARCH AND DEVELOPMENT IN METALLURGY. Progress Report for November 1958
The fabrication of U-2 wt.% Zr clad with Be by coextrusion is presented. A program to produce and evaluate Be which possesses a three-dimensional random texture even after hot working is described. Two methods are being tried to achieve this. Data are presented on the mechanical properties of Be rod made by upsetting and then extrusion. A program concerned with investigating am economical method of producing Th-U alloy fuel slugs by casting to size is reported. Zirconium and stainless steel have been dipped into molten U at 1150 deg C to determine the amount of attack on these metals by molten uranium. An attempt to bond a complete sandwich (V, U, Fe, U, Zr, U, Ti, U, and Nb) by heating to 750 deg C and slow cooling resulted in bonding some of the pieces into sandwiches. A detailed investigation of the 3/2 U + MoO/sub 3/ = Mo + 3/2 UC/sub 2/ reaction has been made. Work is continuing on the corrosion testing of Th alloys prepared by arc melting, including series of Th - Zr, Th - U, Th - Si, and a ternary series of Th-U-Zr. Samples of Y have been prepared for cold rolling, annealing and recrystallization. (W.L.H.)
