【Abstract】 Crystallization phases, morphologies, and electronic structures, as well as thedistribution of metalloid atoms in the nanocryatalline Fe-Cu-Si-B alloys were studied bymeans of XRD, TEM and TMES. The lattice constants of α-Fe(Si) in the alloys may reduceobviously with the growth of grains. The B atoms in the alloys exist in two states and they re-main unchanged in feature as grain growth; while Si atoms occur short range order and itchanges over the grain growing.更多还原
