ժҪ The corrosion behavior study was conducted on a novel Fe77Mo5P9C7��5B1��5 in-situ metallic glass matrix composite (MGMC). This composite sample was developed by introduction of bcc ��-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 ��-Fe dendrites in the MGMCs.
