Austenitic stainless steel of Types 304 and 316 used in Liquid-Metal Fast-Breeder Reactors (LMFBRs) is subjected to sodium at elevated temperatures and to complex stress conditions. As a result, the materials can undergo compositional and microstructural changes as well as mechanical deformation by cyclic fatigue and creep processes. Information is presented on the low-cycle fatigue and creep-rupture behavior of the steels in the solution-annealed condition and after long-term exposure to flowing sodium. The nonmetallic impurity-element concentrations in the sodium were controlled at levels similar to those in EBR-II primary sodium.
