Abstract
In a process for the development of cubic texture in iron-silicon alloys containing 2.5-4% of silicon, the material is hot-rolled to an intermediate gauge, annealed, e.g. at 1400-1800 DEG F., cold rolled with a reduction of 55-80%, annealed in hydrogen in the temperature range 2200-2350 DEG F. whereby the carbon content is reduced, and then given a cold reduction of 75-90% to final size. The sheet is then given a primary recrystallization anneal either box or continuously in the range 1300-1700 DEG F. followed by secondary recrystallization at 1900-2300 DEG F.; these two treatments may be combined, primary recrystallization occurring during heating to the secondary recrystallization temperature. The final heat-treatment is preferably carried out in an atmosphere of hydrogen or a non-reactive gas such as argon or helium, the atmosphere containing a small amount of a highly-polar compound such as hydrogen sulphide, oxides of sulphur or oxides of carbon or mixtures of these. As exemplified an annealing separator of magnesia containing a small amount of sulphur is used in a hydrogen atmosphere.
