Effect of Temperature and Strain Rate on Low-Cycle Fatigue Resistance of AISI 304, 316, and 348 Stainless Steels

Source

Results are reported of strain-controlled, low-cycle fatigue experiments conducted on annealed AISI 304, 316, and 348 stainless steels at temperatures of 430, 650, and 816 C with strain rates of approximately 4 × 10-3, 4 × 10-4, and 4 × 10-5 s-1. The investigation generally shows that fatigue life measured in terms of sustained loading cycles is affected adversely by the increase in temperature and by the decrease in strain rate. The test results were generated with servo-controlled, hydraulic testing machines using inductively heated hourglass-type specimens. Cyclic stress-strain data are compared with monotonic stress-strain data obtained from tension tests performed at the same temperatures and strain rates.
