| Abstract Scope |
For additive manufacturing techniques like laser powder bed fusion, the link between microstructure and processing parameters is complex, with melting, resolidification, and subsequent cooling taking place at much higher rates and with much higher thermal gradients than in traditional metallurgical processes. Advanced X-ray characterization techniques, such as those available at the SSRL, can illuminate not only the detailed microstructure in the final part but, using high speed X-ray characterization we can nondestructively probe the dynamics of the melting and resolidification. High speed X-ray diffraction shows the melting and resolidification along with any changes in phase or microstructure, while high speed imaging can observe the dynamics of the vapor depression and potential void formation. These provide a direct measure of the subsurface thermal history. This talk will include an overview of both in-situ and ex-situ characterization techniques available at SSRL and their potential impact on additively manufactured materials. |
