    Abstract

    Fe-Mn alloys in biomedical materials application are prospective to be developed because of their properties, such as biodegradable and compatible with MRI (Magnetic Resonance Imaging). Many researches were focused on degradable rate of this alloy in order to adjust with healing time process at about 12 months as coronary stent. Several methods were investigated to produce excellence properties for this application, such as addition of alloying elements and powder metallurgy with mechanical alloying (MA). In this study, carbon is added as an alloying element. Material compositions were set to the value of Fe-25%Mn-1%C and Fe-35%Mn-1%C with MA or Non-MA treatment. Specimens were compacted for 15 minutes and followed by sintering process in vacuum furnace. XRD pattern and Ferrite Scope test showed the effects of the addition of Carbon allowed to produce a material that is dominated by the austenite phase (99%) with manganese content lower than previous studies. This result could reduce the toxicity issue from Manganese content in alloy. MA treatment gave smaller particle size, lower porosity and reduce corrosion rate than alloy material that formed without MA treatment. This study offers an easier fabrication process and produces alloys with manganese content lower than previous studies and dominated by Austenite phase.
