The yield strength of solution-annealed 21-6-9 austenitic stainless steel was determined over a wider temperature range (-195 to 1100/sup 0/C) than has been previously reported. The most noteworthy characteristic of the variation of yield stress with temperature was the dramatic decrease in yield strength from -195/sup 0/C to 300/sup 0/C. The strain-rate sensitivity exponent, N, was determined using strain-rate change tests. A plot of N vs temperature showed that n dramatically increased at about 850/sup 0/C and that N is approximately independent of strain (structure). 3 figures.
