Stress-strain-temperature hysteretic behavior is examined in an Fe-Cr-Ni-Mn-Si polycrystalline shape memory alloy during thermomechanical cyclic loading, each cycle of which consists of isothermal loading/unloading followed by isostatic heating/cooling. Transformation start and finish lines are first determined in the stress-temperature plane, which are revealed to be less cycle dependent. Hysteretic behavior is, on the contrary, shown to be highly cycle dependent. Its strong dependence on hold stress as well as on temperature range is also examined. The martensite start line is clearly determined above the yield stress of the parent phase.
