ANALYSIS OF VALENCE ELECTRON STRUCTURE ON Fe3AlCx PRECIPITATED FROM C-ALLOYED IRON ALUMINIDES

Carbides of Fe3AlCx precipitated from iron aluminides can strengthen the matrix; the empirical electron theory (EET) was applied to analyze the attribute of carbides in the paper, giving theoretical explanation on the matrix and precipitation. Valence electron structure (VES) of Fe3AlCx was studied in detail, comparison with the iron aluminides matrix, the hard and brittle phase of Fe3AlCx can be interpreted form the viewpoint of valence electron structure.
