Abstract: The wear behavior of nanostructured hypoeutectic Fe94.3B5.7 alloy was investigated in comparison with coarse grained counterpart. The friction coefficient of the Fe94.3B5.7 alloy changed slightly with grain size. While the wear rate decreased as the grain size decreased to nano scale. Both Fe2O3 and Fe2SiO4 oxides were found on the worn surfaces in the nanostructured Fe94.3B5.7 alloy, but only a few oxide films were observed for the coarse grained counterpart. These results suggested that the nanostructured eutectic was conducive to forming oxide films on the worn surface of the Fe94.3B5.7 alloy, and improved the wear resistance.
