Abstract

Various local testing methods, namely, nanoindentation, compression and bending tests of micropillars were used to better understand the influence of ternary Cr atoms on the extrinsic and intrinsic mechanical properties of Fe3Al intermetallics with the D03 super lattice.Using such local techniques enables us to quantify the influence of Cr on the enhancement of the YoungD's modulus. Furthermore, the effect of Cr on the yield stress, strain hardening and appearance of slip traces was studied based on the stress-strain curves and secondary electron micrographs of the bended and compressed pillars.
