words: molten aluminum; aluminum alloy; corrosion; wear; synergistic effect; intermetallics 1 Introduction Corrosion-wear is one of the extreme states present in engineering process. Different from... and molten Al. The corrosion mechanism of molten Al is essentially similar to hot-dip aluminizing, so many analyses on the interface reactions, the formations of Fe-Al intermetallics and the corresponding......

modification of the amorphous powder was performed through annealing and post milling.Annealing above the crystallization temperature(Tx) not only induced nanoscale intermetallics to precipitate in the amorphous powder,but also increased Cu atomic percentage within the residual amorphous phase.Post milling induced the amorphization of the nanocrystal intermetallics and the formation of Cu9Al4 from......
