Notes:
Cyclic tests have been carried out on a hot work tool steel (H13) over a range of temperatures using different waveforms. At a temperature of 125°C, a slow-fast wave resulted in lower crack propagation rates than those with a balanced (or symmetrical) waveform. However, at 500°C normal fatigue crack propagation behaviour was observed in which the slow-fast wave was more damaging than a balanced waveform at the same frequency. Dynamic strain aging is attributed to the reversed crack propagation effect at 125°C.
