Abstract: A method for producing a soft magnetic material consisting essentially of up to 0.05% carbon, up to 1.0% manganese, up to 0.5% sulfur, up to 0.5% silicon, from 0.5 to 1.5% phosphorus, balance iron and residuals. The method comprises the steps of: blending iron powder and phosphorus-bearing powder into a mixture containing from 0.5 to 1.5% phosphorus; pressing the blended mixture; and sintering the mixture in a non-oxidizing atmosphere at a temperature and for a period of time sufficient to produce a density of at least 7 grams per cubic centimeter. The sintering temperature is at least 2200.degree. F. The soft magnetic material is characterized by a magnetizing force to reach 10 kilogauss of no more than 2.0 oersteds, and a coercive force from 10 kilogauss of no more than 0.9 oersted.

Abstract: A process for producing electromagnetic silicon steel having a cube-on-edge orientation. The process includes the steps of: preparing an aluminum-bearing melt of silicon steel; casting the steel into an ingot; soaking the ingot at an elevated temperature; hot rolling the ingot into a bar of less than 2 inches in thickness; hot rolling the bar into a band of less than 0.2 inch in thickness, when the bar is at a temperature of from 1800 to 1900.degree.F; heat treating the steel; cold rolling the steel at a reduction of at least 75%; decarburizing the steel; and final texture annealing the steel.
