英文摘要	A novel Fe-30Mn-1C alloy was fabricated by vacuum induction melting, and its mechanical properties, magnetism, degradation behavior in simulated body fluid and in vitro biological properties were studied. The results showed that Fe-30Mn-1C alloy had better mechanical properties than those of Fe-30Mn alloy and 316L stainless steel due to the addition of carbon. Compared with Fe-30Mn, Fe-30Mn-1C alloy showed lower magnetic susceptibility, which is beneficial to the MRI compatibility. Electrochemical impedance spectrum (EIS) results showed that Fe-30Mn-1C alloy had lower polarization resistance, resulting in higher degradation rate compared with Fe-30Mn alloy, which was further confirmed by the static immersion test. The in vitro test results indicated that Fe-30Mn-1C alloy had lower hemolytic ratio, better anticoagulation property and less platelet adhesion as well as good cell compatibility, meeting the basic requirement on medical implants.
