| Abstract Scope |
Fe–Mn–Si-based shape memory alloys (SMAs) show promising biocompatibility and can be processed using different additive manufacturing (AM) methods such as wire and arc additive manufacturing and laser powder bed fusion. While Ni-Ti SMAs are widely used in biomedical devices, concerns about nickel toxicity and the presence of permanent implants motivate the development of biodegradable alternatives. Iron-based alloys offer favorable mechanical properties and biocompatibility, but their corrosion behavior must be tailored to match healing times. Fe–Mn–Si SMAs exhibit a reversible γ–ε phase transformation and promising mechanical performance, yet their biomedical application especially combined with the design freedom of additive manufacturing remain largely unexplored. The presented study investigates microstructure design via additive manufacturing to tailor corrosion behavior and functional properties for biodegradable biomedical applications. |
