Metallic Biodegradable Coronary Stent: Materials Development

Abstract

By taking 316L stainless steel as reference for mechanical and physical properties, a series of iron-manganese alloys was developed. Four alloys with manganese content ranging from 20 to 35wt% were prepared. Their microstructure, mechanical and physical properties were carefully investigated. Results show that the developed alloys possess mechanical and physical properties suitable for the development of biodegradable coronary stents.
