“…For orientation microscopy, an EBSD detector (TSL/EDAX) was installed at a position opposite the FIB column. This position allows the quick and precise change between FIB milling for serial sectioning (sample at 36 • ) and EBSD mapping (sample at 70 • ) [25,[40][41][42][43]. The spatial resolution of 3D pixels for EBSD analysis can be as small as 50 × 50 × 50 nm 3 .…”

We have studied the nucleation and growth processes in a chemical vapor deposition (CVD) diamond film using a tomographic electron backscattering diffraction method (3D EBSD). The approach is based on the combination of a focused ion beam (FIB) unit for serial sectioning in conjunction with high-resolution EBSD. Individual diamond grains were investigated in 3-dimensions particularly with regard to the role of twinning.

“…Scheriau and Pippan 2) reported the influence of grain size on orientation change in polycrystalline copper, nickel and iron. The orientation gradient around a hard particle in a warm-rolled Fe3Al-based alloy 3) and the distribution of geometrically necessary dislocations in dual-phase steels 4) were studied by three-dimensional EBSD. These results suggest that intragranular misorientation is a key indicator for material properties and microstructure evolution.…”

The mechanism and the effective factors for the development of intragranular misorientations due to kinking is studied by a crystal plasticity finite element method. A single crystal with hexagonal close-packed (HCP) structure in which only basal slip system is activated is used as a model material. To activate basal slip system, the initial crystal orientations are set to be the ones whose basal planes are slightly deviated from the compressive direction. The result shows that basal slip and the development of intragranular misorientations are sometimes localized near the center of the specimen depending on the initial deviation angle, strain hardening rate, and strain rate sensitivity. The mechanism is discussed in terms of the nonuniform stress distribution and lattice rotation. The effect of slight changes in the boundary conditions shows significant effect on the positions of slip localization. In summary, the present numerical results suggest that there are a number of effective factors for the development of the intragranular misorientations due to kinking including initial crystal orientation, material parameters, and boundary conditions.
