摘要：

Investigations of Fe segregation and competitive Fe-Cu segregation at Al grain boundaries was performed using Mossbauer spectroscopy. An additional component of the Mossbauer spectra was discovered. It was identified as corresponding to Fe atoms segregated at the grain boundaries (GB) of Al. It was shown that Cu atoms drive out Fe atoms from GB if the Cu concentration is several times more than Fe one. (C) 1998 Elsevier Science B.V. All rights reserved.
