Scientists at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), under the Department of Science & Technology (DST) has developed new generation Iron-Manganese based alloys for biodegradable metal implants for use in humans.
About:
Iron-Manganese based alloy Fe-Mn (having Mn composition of more than 29% by weight) is a promising biodegradable metallic implant which exhibits single austenitic phase (non-magnetic form of iron) with MRI compatibility.
The alloy also showed a degradation rate in the range of 0.14-0.026 mm per year in the simulated body fluid, which means that the Fe-Mn alloy exhibits mechanical integrity for 3-6 months and completely disappears from the body in 12-24 months.
The newly developed Fe-Mn based alloys are suitable for biodegradable stent and orthopedic implant applications.
