Atomic force microscopy and transmission electron microscopy identification of deformation twinning in the Cr2AlC MAX phase
Source abstract
Abstract
International audience ; Elementary deformation mechanisms have been investigated in a single-crystalline Cr2AlC MAX phase. Plasticdeformation has been induced at room temperature by spherical nanoindentation, with a crystal orientationchosen to minimize basal slip and to promote local crystal reorientation. The combination of Atomic ForceMicroscopy (AFM) surface observation, Transmission Electron Microscopy (TEM) characterization and Auto-mated Crystal Orientation Mapping (ACOM) in a same region has provided a full 3D characterization of thedeformation microstructure. Localized and isolated deformation twins have been identified below the indents.The whole microstructure consists in interactions between dislocations and {1124} twin variants. The TEManalysis also revealed activation of a 13 〈1120〉{1103} slip system never reported before in a MAX phase.
