Effects of N2-H2final annealing on the magnetic properties of Al-bearing high permeability grain oriented Si-Fe

The effect of N2in the anneal atmosphere on the texture and the associated magnetic properties of Al bearing 3% Si-Fe was investigated. Cold rolled/decarburized samples were annealed in either 100% H2or a mixture of 25% N2-75% H2. Orientations of grains were determined using selected area electron channeling. Misoriented (i.e., not
