ChE Seminar: Grain Boundary Segregation for Nanostructured Metal Printing, Dr. Christopher A. Schuh

How Grain Boundary Segregation Enables 3D Printing of Bulk Nanostructured Metals Dr. Christopher A. Schuh Massachusetts Institute of Technology ABSTRACT: When the grain size of a metal is refined to a scale on the order of just a few nanometers, its strength, hardness, wear resistance, and other properties improve in dramatic ways. There is therefore significant interest in designing and deploying such nanocrystalline alloys for structural applications. However, refining the grain structure is a struggle against equilibrium, and nanocrystalline materials are often quite unstable; the grains...
