报告摘要：

Atom Probe Tomography (APT) has become indispensable for decoding nanoscale phenomena thatgovern the performance limits of advanced structural and functional materials. The newly launched Invizo6000 “ADAPT" platform at National University of Singapore further elevates this capability, enablingunprecedented atomically-resolved 3D chemical mapping and analysis of various types of defects* withenhanced sensitivity, field of view, and operational robustness. In this seminar, I will demonstrate howInvizo-enabled defect analysis, including solute segregation, short range ordering or clustering, dislocationassociated chemistry, and nanoscale precipitation or inclusions, provides critical insights into processstructure-property relationships in metal additive manufacturing (AM). By integrating APT withCALPHAD, melt-pool modelling and correlative microscopy, we establish a pathway for rational alloy ancprocess design. This talk highlights how APT-driven analysis of defects could facilitate the discovery ancdevelopment of strong, tough yet defect-tolerant AM metals for extreme environment.
