Abstract

Using alloy design, an Fe₇₇Mo₅P₉C_7.5B_1.5 bulk metallic glass matrix composite reinforced by in situ formed ductile α-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 α-Fe dendrites accounts for the significant enhancement of the plasticity.
