Using alloy design, an Fe77Mo5P9C7 B-5(1) (5) bulk metallic glass matrix composite reinforced by in situ formed ductile alpha-Fe dendrites has been developed In contrast to the monolithic Fe-based bulk metallic glasses that usually Fail in brittle fracture, the resulting composite shows a significant plastic strain of more than 30% as Well as a high fracture strength of over 3 0 GPa. The in Situ formation of the ductile alpha-Fe dendrites accounts for the significant enhancement of the plasticity (C) 2009 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
