This document reports the effects of high strain rate (10/sup 2/ to 10/sup 4/ s/sup -1/) on the yield strength of 21-6-9 austenitic stainless steel. The reported yield stresses are appropriate to the temperature range from ambient to 750/sup 0/C. The high strain-rate stresses were determined from Hopkinson split-bar tests. The high strain-rate data are compared to the strength of 21-6-9 of identical structure and composition at lower rates (e.g., 10/sup -4/ s/sup -1/). Such comparison provides insight into the rate dependence, at various temperatures to 750/sup 0/C, of plastic flow over a wide range (eight orders of magnitude) of strain rate.
