Corrosion fatigue behavior of electron beam melted iron in simulated body fluid

Abstract Pure iron is very attractive as a biodegradable implant material due to its high biocompatibility. In combination with additive manufacturing, which facilitates great flexibility of the design, it possible selectively adjust microstructure in process, thereby control corrosion and fatigue behavior. present study, conventional hot-rolled (HR) pure compared manufactured by electron beam melting (EBM). The microstructure, behavior properties were studied comprehensively. investigated sample conditions showed significant differences microstructures that led changes properties. EBM significantly lower strength HR iron. These different responses observed under purely mechanical loading well superimposed influence are summarized model describes underlying failure mechanisms.
