Temperature dependence of yielding in austentitic stainless steels
Description
The temperature dependence of yielding is discussed with specific reference to austenitic stainless steels. Tensile yield stress (sigma/sub y/ measurements at 0.2% plastic strain, a strain rate of 0.02 mm/s, and temperatures between 40 and 2950K are reported for a heat of AISI 316 stainless steel. The results are compared with previously published data for the same heat at elevated temperatures, and the yield stress is observed to decrease from 660 MPa at 40K to 102 MPa at 9220K. The decrease is regular, with no obvious anomalies, and apparently no low temperature martensitic transformations at 0.2% strain. The merits and limitations of various expressions for describing the temperature dependence of the yield stress are then evaluated
