    摘要: This invention provides methods for rapidly heating a metal part of varying thickness. In general, the invention provides methods comprising heating the thicker section(s) of the part by induction heating and the thinner section(s) by resistance heating. Induction and resistance heating both quickly heat metals and because each is easily controlled individually, the part can be uniformly heated for hardening and tempering.
