Oxidation resistant Hastelloy-C is the material presently used to clad a small radioisotopic heat source. Inconel-600 has properties and composition similar to Hastelloy-C and is under consideration as an alternate clad material. To serve this purpose, the material must be compatible with the underlying T-111 alloy strength member. Upon completion of compatibility studies, metallographic examination of the specimens revealed reaction zones that appeared to be influenced by time and temperature. The widths of the zones were determined by linear measurements from photomicrographs. These data were used to determine rate curves for the reaction at 1000, 1100, 1225/sup 0/C. The activation energy for the reaction was determined from these rate curves. The data for Inconel-600, when compared to previously accumulated data for Hastelloy-C, indicated that Inconel-600 can be substituted for Hastelloy-C and will pose no compatibility problem in the heat source.
