Popis: The title problem was discussed by performing a series of total-strain controlled cyclic tests under uniaxial tension-compressoin and circular strain paths. Constant strain rate of 0.2% /min was specified throughout the tests. The effects of strain amplitude history were examined by changing the strain amplitude between 0.2% and 0.4% (step-up and step-down test) at room temperature, 400°C and 600°C. For temperature history dependence tests, the temperature was changed between 200°C and 600°C, 400°C and 600°C, 500°C and 600°C, respectively by specifying a constant strain amplitude of 0.3%. It was observed that though the history of the preceding cycles with smaller strain amplitude or preceding cycles at lower temperatures was erased by the subsequent cycles with larger strain amplitude or at higher temperatures, the preceding cycles with larger strain amplitudes or those at higher temperatures had considerable effects on the subsequent cycles.
