PROCESSING OF IRON COBALT LAMINATION MATERIAL FOR HYBRID TURBO-ELECTRIC COMPONENTS

Abstract:

Methods for processing an iron cobalt alloy, along with components formed therefrom, are provided. The method may include: pre-annealing a sheet of an iron cobalt alloy at a pre-anneal temperature (e.g., about 770.degree. C. to about 805.degree. C.); thereafter, cutting a component from the sheet; thereafter, heat-treat annealing the component at a treatment temperature (e.g., about 845.degree. C. to about 870.degree. C.) for a treatment period (e.g., about 1 minute to about 10 minutes); and thereafter, exposing the component to oxygen at an oxidizing temperature to form an insulation layer on a surface of the component.
