Metallic materials play an essential role as biomaterials to assist with the repair or replacement of bone tissue that has
become diseased or damaged. Plates, screws and pins used to secure serious fractures must be removed by a second
surgical procedure after the tissue has healed sufficiently. Repeated surgery increases costs to the health care system and risk
to the patient. To overcome these problems biodegradable materials can be used which temporarily support tissue healing and
are completely degraded in certain time. Fe-Mn alloys are promising candidates for biodegradable metallic materials because
of excellent mechanical properties, which are usually obtained by multi stage forming processes. However, biodegradability
rate is usually not sufficient and last too long, degradation is not continuous and sometimes flakes are formed. The main goal of
current research is to understand different production processes: casting, hot rolling and annealing; on the corrosion behavior
of the biodegradable FeMn17 alloy due to the formation of less-corrosion-resistant deformational martensite. With additions
of Mn the mechanical properties increase and the corrosion resistance decreases. The process parameters influenced the
biodegradability as well as the mechanical properties. The produced material, cast and hot rolled, has interior stress and that
increases the biodegradability, though the annealing process increases the stability of the material and the corrosion resistance.
