Paper Abstract

It has been shown with the help of x-ray researches that the electronic structure of structural components formed in a surface layer of steel during laser alloying differs form that of similar structural components formed in equilibrium conditions. Saturation of a solid solution beyond the limit solubilities during laser alloying leads to some increase of electron localization on atoms. The analysis of distribution of electronic density in an elementary cell of a solid solution shows that some part of atoms of boron is dissolved in a solid solution on the basis of iron by replacement. The nonequilibrium process of cooling after crystallization leads to appreciable change of an electronic structure of boron iron Fe2B. The comparison of boron iron, formed in equilibrium conditions, with boron iron form a laser alloyed layer shows that in an elementary cell of latter the distribution of electronic density is more dim, that allows to speak about some decrease of a degree of electron localization on atoms.
