"In order to reduce iron losses in non-oriented electrical steels for high-frequency motors applications, several alloy elements, such as silicon and aluminum etc., have been added in the steels to lower eddy losses. However, the magnetic flux density of these sheets seriously drops due to iron fraction reduction and texture change. In this study, the effects of phosphorus-addition on microstructure and texture have been investigated by using OM, X-ray, and EBSD analyses. The results indicate that the texture of steel with phosphorus content is favorable compared with non-P-added steel. A higher fraction of the Cube texture ( {100}<001> ) has been observed in the P-added steel, and the {111}<112> component, which is harmful to magnetic properties can be suppressed after annealing process. These analytic results are useful in developing high graded non-oriented electrical steels in the future."
