Abstract
One of the most important research policy of the Institute of Metals and Technology is development of methodology of micro and nanostructure characterization of metallic materials on the highest level.
In the frame of the project "Electron spectroscopy of micro and nanostructures of metals and alloys" the development of methodology of investigation the relaxation and reconstruction process of FeSi surface is planed. FeSi alloys will be manufactured in the Laboratory at IMT.
Process of surface relaxation and reconstruction is induced by surface segregation of impurity elements. Our extensive previous investigations showed that surface active elements segregated to the free surfaces and induced grain growth of grains of (100)(001) crystallographic orientation, these findings are also reported by several authors.
In our previous investigation we experimentally established the surface reconstruction phenomena of grains of crystallograpic oirentation (110)(001) to grains (100)(001). The phenomena will be investigated in details by integration of advanced analytical methods for surface analysis, hihg resolution Auger electron spectroscopy HRAES, scanning Auger microscopy SAM and high resolution electron back scattered difraction EBSD as well as combination of electron and wave dispersive spectroscopy ED/WD. Surface segregation of surface active elements, such as Sb, Sn, Se and Te on the FeSi surfaces and their interaction with S and C will be studied in details as well as recrystallization, grain growth and formation of nano and micro texture and surface reconstruction.
