A Journey from Berkeley to Daejeon via Columbus

Abstract

Evolution of modern manufacturing technology requires ever-increasing international competitiveness, requring sustainability of the materials and processing technologies. In order to achieve this goal, new materials and manufacturing processes should be developed economically in the production facility constraints avaialable. Variuos studies investigated at the laboratory level will be introduced in the present talk; material characterization of ammonium perchlorate base composite using the hydroxyl-terminatedpolybutadiene as binding materials, production of grain-refined copper wires through a non-circular drawing and a new hybrid process containing of rolling, equal channel angular processing, and drawing with thermomechanical treatment, etc. In addition, development of three dimensional metal printing machine using directed energy deposition (DED) and powder bed fusion (PBF) techniques will be introduced. Some important issues involved with developing sustainable materials processing technologies will be addressed from various perspectives as well.
