EFFECT OF SUBCRITICAL QUENCHING ON THE FATIGUE LIMITS FOR CRACK INITIATION AND FOR FAILURE OF PRESS FITTED PARTS OF AXLES

To improve the fatigue limits of press fitted parts of axles by subcritical quenching, that is, water quenching from the temperature just below the Asubc1 point, the effect of heat treatment on the effects of the heat treatment conditions on microstructure, hardness, residual stress distribution, and rotating bending fatigue limits for crack initiation and for failure were examined. Unnotched, notched, and 50 mm diam fitted specimens of 0.35, 0.45, and 0.40% C unalloyed steels, respectively, were used in the investigations. Results are reproduced and discussed.
