Abstract:The microstructure and phase constitution of Sn contaminants on the surface of 304 stainless steel were investigated and the fatigue property was evaluated. It was revealed that the pure tin contaminated 304 stainless steel by the formation of plate-type and block interfacial (Fe, Cr) Sn-2 layer. The fatigue failure of 304 stainless steel with Sn contamination is due to the crack origin from Sn contaminants and the mechanism could be related to the initiate and movement of dislocations.
