As Metal Additive Manufacturing (MAM) continues to develop, materials scientists and engineers will need a more mindful understanding of their feedstock powders’ mechanical, thermal, and optical properties. This is due to the fact that acute discrepancies in powder production and powder preparation can cause dramatic behavioral discrepancies in resultant MAM-made materials – especially in materials fabricated by solid-state joining. While significant gains have been achieved within the domain of standardizing the methodologies involved with thermal and optical characterization of MAM feedstock powders, significant challenges have prohibited affordable and readily available standardized mechanical characterization methods. In order to make necessary advancements in the microscopic mechanical characterization of metal powder particles, the case of determining stress-strain curves of metal powder particles via nanoindentation is considered herein.
