Abstract

The antimony surface segregation was investigated on surfaces of a polycrystalline Fe-Si alloy with 0.05 wt. % Sb, under UHV conditions, in the temperature range from 450 to 950 °C. The grain boundary segregation in experimental alloys was negligible. It was concluded that the texture formation results from orientation-dependent effects of antimony on the surface energy and through them on grain boundaries. Controlled surface segregation promotes the selective grain growth.
