Correlations developed for void swelling and irradiation creep often arise from two separate data bases and sometimes are not well-matched, reflecting apparently minor but actually significant differences in environmental history. Previously published correlations are very empirical in nature and reflect prevailing misconceptions about the parametric sensitivity of swelling and irradiation creep. In this study a well-defined data base for swelling of 20% cold-worked AISI 316 is used in conjunction with the latest insights on swelling and creep to develop two matched dimensional change correlations for temperatures in the range of 300 to 650/sup 0/C. The new creep model, in particular, is much simpler than the complicated empirical correlation published earlier for this steel. 18 refs., 6 figs.
