The temperature dependence of the multiaxial cyclic behaviour of type 316 stainless steel was elucidated experimentally. Cyclic tests under constant total-strain amplitudes were performed for uniaxial tension-compression and circular strain paths at several temperatures ; room temperature, 200℃, 400℃, 500℃, 600℃ and 700℃. The strain amplitudes of the cycles were specified to be 0.2, 0.3 and 0.4% under constant strain rate of 0.2% /min. It was observed that though strain hardening for circular cycles was larger than that of the tension-compression cycles at every temperature, the effect of nonproportionality in cyclic hardening decreased with the increase in temperature. The cyclic hardening was significant particularly in the temperature range between 400℃ and 500℃.
