AbstractThis paper studies the formation mechanism of fine granular area (FGA) in high-strength steels and predicts the threshold value of its formation. Fatigue experiments are carried out by using rotating bending and ultrasonic fatigue testing machines on a high carbon chromium steel (GCr15) with three different heat treatments. The results show that the range of stress intensity factor at the periphery of FGA (Delta K(FGA)) keeps constant with an average value of 5.2 MPa m(1/2), which is close to the traditional crack growth threshold (Delta K(th,0)), 5.0 MPa m(1/2). A theoretical model based on the plastic zone at crack tip is proposed to predict the value of Delta K(FGA) and the predictions are in good agreement with experimental data. (C) 2011 Elsevier B.V.
