Irradiation and Thermal Creep of a Titanium-Modified Austenitic Stainless Steel and Its Dependence on Cold Work Level
Schellenberg, F. M.
A titanium-modified austenitic stainless steel similar to the fusion PCA alloy was creep tested at three cold work levels under both thermal aging and neutron irradiation conditions. The creep behavior exhibits a complex nonmonotonic relationship with cold work level that reflects the competition between a number of stress-sensitive and temperature-dependent microstructural processes. Increasing the degree of cold work to 30% from the conventional 20% level was detrimental to its performance, especially for applications above 550°C. The 20% cold work level is preferable to the 10% level, in terms of its initial strength, in-reactor creep and swelling response.
