Nanomechanical testing study of the elementary deformation mechanisms in the Ti2AlN and Cr2AlC MAX phases

Conference Dates

September 29-October 4, 2019


Abstract: Deformation mechanisms in MAX phases are still not well understood. The complex mechanical behavior of these materials, including mechanical hysteresis, arises both from their crystallography, with a nanolayered structure alternating nitride or carbide layers with metal atoms layers, and from their macroscopic polycrystalline structure, composed of platelets-like grains. In order to distinguish from these two contributions, we focused our study at the sub-micrometer scale, in order to probe the mechanical response of individual grains.
