PREFERRED ORIENTATION IN ZIRCONIUM ALLOY WIRE FUEL ELEMENTS
Texture determinations were made of the claddings and cores of wire fuel elements consisting of either 3 or 5% Zr-Sn cladding on cores of 20% U - Zr. Results are given for specimens worked at various temperatures from 600 to 900 deg C and subjected to reductions of area from 59 to 97%. A single (1010) fiber texture was found in the cladding after hot swaging. Recrystallization abcve the swaging temperature produced a duplex (101-bar0) (112-bar0) fiber texture. A beta heat treatment appeared to randomize the texture. The texture of the alpha -Zr phase in the core corresponded to that predicted by assuming the conventional BCC fiber texture and applying Burger's transformation mechanism for zirconium. The orientation study of the epsilon phase in the core was somewhat questionable. Tentative results indicated a (101) fiber texture for this phase in the "as hotswaged" condition. (auth)
