摘要：

The effect of additions of antimony (0.05% Sb) to silicon steel on the improvement of the electrical properties of non-oriented steel sheet was investigated. Measurements of surface segregation of Sb were performed under UHV conditions in the temperature range from 450 to 900 degrees C, using AES and TDS. Maximum equilibrium surface segregation of antimony was determined at 700 degrees C. At higher temperatures, T> 800 degrees C, the desorption of antimony from the surface was measured. The grain boundary segregation was negligible and we can conclude that the texture formation, rich in (100) grains, results from the effect of the orientation dependent surface segregation of Sb. This segregation causes differences in surface energies and the stability of different grains. Controlled surface segregation promotes selective grain growth improving the electrical properties of non-oriented steel sheet.
