Abstract Scope |
Printed alloys provide opportunities to build challenging geometries as well as explore processing conditions of non-equilibrium microstructures. Rapidly assessing these microstructures is critical to performance benchmarking and the development of optimized alloys for printing. The length scales of microstructures are comparable to the particle size in the printing process. Nanoindentation, particularly high speed nanomechanical property mapping, combined with correlative techniques such as EDS to assess chemical gradients and EBSD to assess local microstructure and strain can provide unique information at the correct scale. Here, we look at performance of single weld, a 3D printed austenitic alloy, and a repaired part to generate an understanding of local structure-processing-performance characteristics. |
