1. The rate of increase in the reheat temperature on the linear segment remains constant (for a periodic loading with higher stress levels) until a critical damage is sustained for the stress in question.
2. The magnitude of Tc for a given stress is independent of the loading history, provided the critical damage has not been sustained for this stress.
3. With decreasing stress Tc decreases slightly. A method for the accelerated determination of Tc from a single specimen for different stress levels has been developed.
4. A method of predicting the fatigue life from the results of short-term tests, which take into account the variation of Tc due to stress level, has been developed.
