Recent Advances in Magnesium Alloys for Biodegradable Implants

NSF ERC for Revolutionizing Metallic Biomaterials


11 AM – 11:50 AM – Friday, March 28, 2014

McNair Hall Auditorium – College of Engineering



The objective of this presentation is to present the cutting-edge discoveries on the development of Mg-based alloys for biodegradable implants in cardiovascular and orthopedic applications. Mg-based alloys have outstanding advantages over the other biodegradable metals such as Fe-based alloys or Zn-based alloys. However, the wide applications of Mg-based alloys are still inhibited mainly by their poor strength and ductility, and high degradation rates. This presentation focuses on how traditional and innovative alloy development strategies  are helping to mitigate/eliminate the global problems rooted in Mg-based alloys. The ultra-strong novel Mg-based alloys (400~600 MPa) developed recently at A&T’s ERC are highlighted and discussed.
