Abstract Scope |
Microstructure and mechanical properties are governed by material composition and processing history. In additive manufacturing, this processing history is complex and varies across multiple length scales, from localised high cooling rates and thermal cycling (including remelting) to longer-term temperature trends across the wider part. In-situ process monitoring tools can quantify this processing history in unprecedented detail, across multiple length and time scales, enabling the prediction of, and potential mastery of, local microstructure and mechanical properties. This talk will describe in-situ monitoring systems to gather this data in laser powder bed fusion and demonstrate the reconstruction of 3D processing history maps to show these local variations. Relationships between processing history, defects, microstructure and properties will be shown. Opportunities and synergies with small scale characterisation methods will also be discussed. |
