Controlling form and microstructure for high-performance additively manufactured parts

Abstract: Metal additive manufacturing (AM) techniques have recently attracted a lot of interest because they offer exceptional control over form and the potential to revolutionize supply chains. However, despite all the hype about AM, it is important to remember that these techniques have serious drawbacks, including limited control over microstructure and potentially low yields. Further, additively manufactured parts often contain pores that degrade the mechanical properties, and especially fatigue performance. In this talk I will summarize our efforts to address problems with pore formation and build failures in electron-beam additive manufacturing, as well as our recent work developing new AM techniques for printing nanocrystalline materials, mesostructured periodic composites, and net-shaped single crystals.

Biography: Dr. Cordero is an assistant professor of Materials Science and NanoEngineering at Rice University. He earned both his B.S. in Physics and his Ph.D. in Materials Science and Engineering from Massachusetts Institute of Technology. After receiving his PhD, Dr. Cordero spent one year as a post-doctoral fellow at the Manufacturing Demonstration Facility of the Oak Ridge National Laboratory. There he developed improved process monitoring, quality control, and microstructure design tools for powder-bed, metal additive manufacturing technologies. Dr. Cordero launched the Additive Lab at Rice University in July 2016. For additional information please visit Dr. Cordero’s website: http://additive.rice.edu/
