ABSTRACT:
A process is described in which an iron-silicon alloy capable of being heat treated to produce a cube-on-edge (110) [001] grain orientation is treated to produce improved core losses when the material is under high operating inductions. The process steps include cleaning the surface of the steel of finish gauge thickness, applying a coating to the surface of the steel which is non-reactive with the surface and promotes decarburization, heating to a temperature sufficiently high to effect secondary recrystallization texture development and decarburization and cooling to room temperature. Data are included which demonstrate the improved core losses exhibited by these materials so treated when tested at high operating inductions.
