ZIRCALOY-STAINLESS STEEL BONDING PROGRAM. First Quarterly Report, December 1960 to March 1961
An investigation was made of the joining of Type 410 stainless steel to Zircaloy-2 by friction-bonding techniques. Prehiminary design was completed on a full-scale friction-bonding apparatus. An attempt was made to determine a joint design that would minimize Zircaloy-2 upsetting during bonding. Because of their relatively low strength at moderate temperatures, the Zircaloy members were extruded into the bore of the stainless-steel tubing. By inserting a mandrel into the bore of the joining members, this extrusion effect was virtually eliminated. In all specimens, regardless of the extent of bonding, shearing of the Zircaloy was noted. The effects of surface preparations and rolling parameters were stadied in an effort to join the Zircaloy-2 and stainless steel by cold-rolling techniques. Results showed that machined surfaces yield a greater degree of joining than those subjected to either belt abrading or commercial Zircaloy-2 etchants. The rolled taper specimens resulted in extreme cracking of both materials at the specimen ends. A study is being conducted to determine ths feasibility of employing explosive techniques for the joining of Zircaloy-2 to stainless steel. (M.C.G.)
