INFLUENCE OF LOW AL CONTENT ON ANOMALOUS GROWTH IN 3-PERCENT SI-FE MAGNETIC SHEETS

In order to get {100}[001] final texture in electrical 3% Si-Fe sheets, a combination of cross-rolling and inhibition as cube nuclei selection steps before the surface energy effect is attempted to provide a process that draws concurrently on the texture results of each mechanism. The effects of aluminium content and the annealing atmosphere on the final magnetic anisotropy have been studied, and indicate a preferential Al content range and a high sensitivity to the annealing atmosphere. This process leads to significant changes in magnetic properties.
