| Abstract: | Atom Probe Tomography (APT) has become indispensable for decoding nanoscale phenomena that govern the performance limits of advanced structural and functional materials. The newly launched Invizo 6000 “ADAPT” platform at National University of Singapore further elevates this capability, enabling unprecedented atomically-resolved 3D chemical mapping and analysis of various types of ‘defects’ with enhanced sensitivity, field of view, and operational robustness. In this seminar, Prof. Tan will demonstrate how Invizo-enabled defect analysis, including solute segregation, short range ordering or clustering, dislocation-associated chemistry, and nanoscale precipitation or inclusions, provides critical insights into process-structure-property relationships in metal additive manufacturing (AM). By integrating APT with CALPHAD, melt-pool modelling and correlative microscopy, we establish a pathway for rational alloy and process design. This talk highlights how APT-driven analysis of defects could facilitate the discovery and development of strong, tough yet defect-tolerant AM metals for extreme environment. |
