An induction hardening heat treatment method comprises the steps of induction heating a metal part or component, particularly a part fabricated of a high strength material, and then exposing the part to a sequence or series of partial, intermittent or interrupted quenches. Such intermittent or interrupted quenching achieves the necessary change in surface temperature with time to achieve a martensitic transformation of the surface adjacent metal or material while minimizing surface to core temperature differentials during the process which could result in cracking of the part, especially if it is fabricated of high strength materials.
