The effect of a temperature change on the in-reactor creep of 20% cold worked AISI 316 stainless steel

Results of a temperature change experiment designed to investigate the effects of prior irradiation temperature on the irradiation creep of 20% cold worked AISI 316 stainless steel are reported. The data indicate that this material exhibits an in-reactor 'temperature memory' effect. After a temperature change, the material creeps as if it were still subjected to its prior irradiation temperature. Specimens subjected to a decrease in irradiation temperature are found to swell more rapidly than materials subjected to a constant temperature irradiation. (Auth.)
