| Abstract Scope |
Metal based additive manufacturing is revolutionizing the manufacturing industry by enabling the printing of large complex geometries that would be impossible through regular machining whilst using a fraction of the material required. Processes such as laser powder bed fusion (LPBF) can lay down micron‑thin layers, building internal cooling channels and lightweight lattice infills, making stronger lighter parts for use in aerospace applications. Methods such as LPBF or spark plasma sintering (SPS) also allow for the production of alloyed parts however, several fundamental aspects of the method powder joining remains an active study. This presentation will highlight recent work conducted at The Tennessee Ion Beam Materials Laboratory on copper alloy LPBF as well as Molybdenum and Tantalum particle sintering kinetics and alloying behaviors at high temperatures. In-situ high temperature sintering is studied in real time through the use of laser induced heating combined with Transmission Electron Microscopy. |
