The corrosion behavior study was conducted on a novel Fe77 Mo3, P9 C7.5 B1.5 in-situ metallic glass matrix composite (MGMC). This composite sample was developed by introduction of bcc α-Fe dendrites as reinforcing phase. The corrosion behavior of this composite was compared to its monolithic counterpart and other Fe-based alloys such as 304L and 2304L stainless steels. The corrosion resistance of MGMCs in H2SO4 solution shows inferior to that of other Fe-based alloys. Experiments suggest that Fe-BMGs samples possess better corrosion resistance property than that of Fe-MGMCs. The possible underlying reasons can be the inhomogeneity induced by the precipitation of α-Fe dendrites in the MGMCs.
