Abstract

A simplistic approach would suggest a greater corrosion rate of an alloy in its nanocrystalline state than in microcrystalline state, due to a larger fraction of grain boundaries (i.e., high energy area) in the former. However, the nature of influence of nanostructure on corrosion does not seem to be similar in all cases. In fact, the nature of influence can be opposite, depending on the type of corrosion and environment-material system. A considerably improved corrosion resistance of Fe-Cr alloys in nanocrystalline state (as opposed that in the microcrystalline state) has been established.
