| Abstract Scope |
The enormous parameter space available in additive manufacturing (AM) processes is challenging to navigate. This is especially the case when we are confronted by novel materials science phenomena arising from the frequency and amplitude of the thermal and stress gyrations imposed by the process. Multi-scale microscopy is essential to enable engineers to ‘see’ the resultant microstructures, create phenomenological models, and ultimately drive computational simulations. This lecture will summarise our recent work combining SEM-based techniques such as electron backscattered diffraction and transmission Kikuchi diffraction with (S)TEM-based imaging and analytical techniques and, critically, atom probe tomography (APT). Work on titanium alloys, aluminium alloys and HEA’s will be included. The increasing power of advanced APT analysis techniques for measuring phenomena ranging from short-range order through to segregation will be featured. |
