FUNDAMENTAL AND APPLIED RESEARCH AND DEVELOPMENT IN METALLURGY. Progress Report for March 1959
Beryllium Metallurgy. The use of the bevatron for the radioactivation analysis of O/sub 2/ in Re is discussed. The cladding integrity and dimensional stability of Be-clad U fuel elements were investigated by thermal cycling. A rolling schedule to achieve random orientation in polycrystalline Re was selected. Hot-pressed, Be-rich Cu alloys were prepared for determination of their mechanical properties in uniaxial tension. Attempts are being made to fubricate dense samples of ZrBe/sub 13/, UBe/sub 13, and (U, Zr) Be/sub 13/ by extrusion. The alloy systems Be - Fe, Be - Co, and Re-Cu were investigated to determine the extent of the beta Be phase field, both in composition and in temperature Uranium Metallurgy. Texture studies were made on U rod extruded at 650 deg C, work on the slow extrusion at 485 deg C was continued, and a U billet containing 990 ppm silicon was cast in preparation for the study of textures resulting from the gamma extrusion. The evaluation of Th - 5 to 15 wt.% U alloy slags produced by arc melting amd subsequent extrusion and induction melting and static casting of sized slugs is reported. The effect of interdiffusion heat treatment, and of subsequent heat treatments, upon the corrosion behavior of Zircaloy-2-clad U-2 wt.% Zr specimens containing 7mil diameter defects extending into the core was studied. Thorium Metallurgy. Castings of Th - U, Th - U - Zr, and Th - Zr alloys were made. Zirconium Metallurgy. The corrosion testing of 12 ternary Zr- base alloys in 900 and 1000 deg F steam at 1500 psi is continuing. Other Problems. Some of the extrusion characteristics of canned Y were determined. The multi-temperature extrusion of stainless steel-clad UO/sub 2/, Mg-clad U, and stainless steel-clad U is reported. The extrusion of thin walled U alloy tubing is presented. (W.L.H.)
