Abstract: Effect of copper content on the texture of two high-silicon non-oriented silicon steels without Cu and with trace Cu was analyzed by EBSD technology, and the microscopic mechanism was also investigated. The results indicate that after high temperature annealing at 1000 ℃, the addition of trace Cu element has an obvious harmful effect on the texture of finished silicon steel product. The high temperature annealing process plays a more full role in optimizing the texture by the shear bands, while such optimizing effect is inhibited obviously by adding of trace Cu to the non-oriented silicon steel, which is attributed to the dispersive distribution of the copper precipitates in the steel matrix.

Key words: copper precipitates, non-oriented silicon steel, texture, shear band, heat treatment
