N2 - The initial strength advantage obtained by the bainitic microstructure, gained by quenching, is lost via cyclic softening. The introduction of a hold period into the cyclic waveform, regardless of its type or duration, significantly reduces fatigue life. Compared to results obtained in air, vacuum enhances life at least two-fold. Both crack initiation and propogation are inhibited in the absence of oxidation. Environmental interaction may well be more important than creep damage in the low-cycle fatigue regime.
