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° C. to about 805° C.); thereafter, cutting a component from the sheet; thereafter, heat-treat annealing the component at a treatment temperature (e.g., about 845° C. to about 870° 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.
Claims18
A method of processing an iron cobalt alloy, comprising:
- pre-annealing a sheet of an iron cobalt alloy at a pre-anneal temperature, wherein the pre-anneal temperature is about 770° C. to about 805° C.;
- thereafter, cutting a component from the sheet;
- thereafter, heat-treat annealing the component at a treatment temperature for a treatment period of about 1 minute to about 10 minutes, wherein the treatment temperature is about 845° C. to about 870° C.;
- and
- thereafter, exposing the component to oxygen at an oxidizing temperature to form an insulation layer on a surface of the component.
