Abstract
Our previous investigations experimentally confirmed the phenomenon of increase of the number of magnetically soft grains of crystallographic orientation (100) on the expense of magnetically hard grains (111), induced by surface segregation obtained by addition of 0.05 % Sb or Sn into the silicon steel. It should be in principle obtained also by deposition of small amounts of surface active elements e.g. Sb or Sn on the silicon steel for non oriented electrical sheets. The aim of the proposal is to investigate the mechanism of surface segregation and its selectivity, the model of ultra thin film growth and atom distribution and the phenomena of the decrease the surface energy of surface grains with (100) crystallographic orientation the effect of surface topology and morphology, and the effect of increased driving force of ferrite grain growth with the aim to understand the selectivity of the grain growth benefical for soft magnetic sheets.
