Title: Heat treating of metallurgic article with varying aspect ratios

Abstract: This invention provides methods for rapidly heating a metal part of varying thickness.

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.
