Title: Microstructural and Micromechanical Characterization of FeCrAl C26M tubes

Abstract

The present report summarizes the nanoindentation characterization of a FeCrAl alloy, C26M in both tube and bar form. The current heat, AC2-B, investigated by electron backscatter diffraction showed a textured system with the cross-section favoring orientations near the [110] and the tube surface near the [111], similar to previous heats of C26M. Nanoindentation with a Berkovich tip measured a similar moduli and hardness for all specimens of ~220 GPa and ~5 GPa, respectively. Spherical nanoindentation was performed on all specimens and orientations. Indentation with a 100 μm tip resulted in a measured moduli and yield strength values of ~215 GPa and ~1.5 GPa for all specimens, respectively, and in agreement with the Berkovich indentation results. Mesoscale tensile bars were laser cut out of a thin piece of AC2-B. Initial tensile testing showed that a minimum gauge thickness/width of 0.05 mm is required to approach more bulk-like conditions.
