the present study investigates the crystal preferred orientation (cpo) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (ebsd) on quartz crystals from north of the renvyle-bofin slide (rbs) nearletterfrack in western ireland. complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...

Based on a survey of the literature on orientation relationships in precipitation systems a unified view of all the kno"rn relationships in b~c/hcp and bee/fcc systems is presented. Within each set of crystal systems, orientation relationships are closely connected by small fixed rotations whose magnitude depends only on crystal symmetries. Close parallels exist between the two sets of crystal ...

The mechanical response of almost pure single-crystal micro-pillars under compression exhibits a highly localized behavior that can endanger the structural stability sample. Recent experiments revealed crystal is very sensitive to both presence quenched disorder in sample, and orientation crystal. In this work, we study influence on large 2-D plane strain FCC with three active glide planes usin...

Abstract When magnetic properties are analysed in a transmission electron microscope using the technique of circular dichroism (EMCD), one critical parameters is sample orientation. Since small orientation changes can have strong impact on measurement EMCD signal and such measurements need two separate conjugate EELS spectra, it experimentally non-trivial to measure as function Here, we develop...
