Slip transfer at grain boundaries and annealing twin was studied in polycrystalline Ni by means of slip trace analysis. or blocking assessed >200 related with geometrical criteria that establish the alignment between active systems across boundaries. It found mainly occurs low-angle regular a Luster–Morris parameter >0.8 stands for best criterion to assess transfer. In case coherent incoherent ...

The interest in the crystallography of structural transformations is driven by emerging capabilities texture control and resulting anisotropy physical-mechanical properties functional materials products. recrystallization cold-drawn Cu Al samples after annealing at different temperatures was studied using EBSD. Equivalent deformation textures are transformed into textures. nuclei formed high-an...

The grain boundary character distribution in a commercial IF steel has been measured as a function of lattice misorientation and boundary plane orientation. The grain boundary plane distribution revealed a relatively low anisotropy with a tendency for grain boundaries to terminate on low index planes having relatively low surface energy and large interplanar spacings. Although the most common g...

The purpose of this paper is to describe the five-parameter grain boundary character distribution (GBCD) of polycrystalline silicon and compare it to distributions measured in metals and ceramics. The GBCD was determined from the stereological analysis of electron backscatter diffraction maps. The distribution of grain boundary disorientations is non-random and has peaks at 36", 39", 45", 51", ...

The geometric determinants of shape decomposition were studied using a performance-based method. Observers' identification of contour segments was shown to be systematically modulated by their curvature properties, and by the geometric properties of the enclosed region. Specifically, negative minima of contour curvature provided the best segment boundaries. Segments with negative-minima boundar...
