Short cracks initiate preferably in persistent slip markings that appear in areas of proeutectoid ferrite embedded in the matrix of tempered bainite. The kinetics of short crack was measured in cycling with constant plastic strain amplitudes. Exponential crack growth was observed. Crack growth coefficient was found to be a function of plastic strain amplitude. The comparison of the short crack growth kinetics with fatigue life curve in the form of CoffinManson law allows determining the parameters of the short crack growth law from the low cycle fatigue experiments.
