| Abstract Scope |
Directed Energy Deposition (DED) is a widely used additive manufacturing technique, allowing for the production or repair of components which, in some cases, can have critical applications. Applied external fields promise to refine the microstructures of the alloys and improve the build quality. To investigate and quantify these techniques, we upgraded our Blowen powder Additive Manufacturing Process Replicator to be able to apply ultrasound to the DED process in operando. With the use of in-situ synchrotron radiography and infrared imaging, we were able to investigate the mechanisms of the phenomena and couple those mechanisms with ex-situ characterisation techniques. These confirmed the microstructural modification of grain size and texture alterations under applied ultrasound. |
