摘要

The use of three-dimensional x-ray structural microscopy for nondestructive investigations of the deformation microstructure under microindents was demonstrated. Point to point, micrometer-resolution x-ray microbeam measurements of local lattice rotations were made for selected positions under 100-mN Berkovich and conical indents in single-crystal copper. Local lattice orientation measurements were used to extract micrometer by micrometer lattice misorientations and rotation axes along x-ray microbeams. Measurements of the deformation microstructure in symmetry and off-symmetry geometries are reported and discussed in terms of their potential for fundamental deformation investigations
