Research Project
Dr Hung-Wei Yen is working with Prof. Simon Ringer on the project “Enabling Materials Design via Atom Probe Microscopy” at the ACMM. The focus will be on solute engineering, control of nanoscale precipitation reactions, segregation and grain boundary engineering. The research will primarily be fundamental in nature and seek to develop understanding and strategies that can expand the property performance space of various engineering alloys.
