Summary:

Various induction hardening metallurgical variables for several induction hardening experiments in hardening gears are outlined and related to heat energy inputs and their effect on the bending fatigue strength of gears. The experiments included residual stress measurements by X-ray diffraction and by sectioning and etching techniques; bending fatigue tests; metallurgical examination comprising micro-hardness traverse tests and microstructure-macrostructure evaluations; and dimensional analysis.Based on the results obtained, it was concluded that detrimental residual tensile stresses in the fillet surface of the tooth and the presence of dark etching transformation products near the surface can affect the performance of induction hardened gears in bending fatigue, and that metallurgical requirements can be specified to improve the reliability of induction hardened gears
