| Abstract Scope |
Metamaterials have demonstrated great specific strength properties, ideal for multifunctional opportunities within aerospace and energy generation industries. However, the high temperature properties of metamaterials are not yet well understood to begin to fully incorporate within load bearing applications. This study experimentally examined the compressive creep rates of additively manufactured Inconel 625 solid specimens and single-cell lattice metamaterial specimens to determine differences in the failure mechanisms. The initial microstructures and defects were analyzed via EBSD and XCT before high temperature testing. The lattice topology was shown to drive the compressive creep rate rather than the base material, by nearly two orders of magnitude. Rupture time was dependent on the relationship between initial load and temperature, with all lattice specimens failing in a buckling fashion. |
