The deformation mechanisms and dynamic recrystallization(DRX)behavior of specifically grown bicrystals with a symmetric 90°and 90°tilt grain boundary,respectively,were investigated under deformation in plane strain compression at 200℃and 400℃.The microstructures were analyzed by panoramic optical microscopy and large-area electron backscatter diffraction(EBSD)orientation *** analysis employed a meticulous approach utilizing hundreds of individual,small EBSD maps with a small step size that were stitched together to provide comprehensive access to orientation and misorientation data on a macroscopic *** slip primarily governed the early stages of deformation at the two temperatures,and the resulting shear induced lattice rotation around the transverse direction(TD)of the *** existence of the grain boundary gave rise to dislocation pile-up in its vicinity,leading to much larger TD-lattice rotations within the boundary region compared to the *** increasing temperature,the deformation was generally more uniform towards the bulk due to enhanced dislocation mobility and more uniform stress *** recrystallization at 200℃was initiated in{1011}-compression twins at strains of 40%and *** 400℃,DRX consumed the entire grain boundary region and gradually replaced the deformed microstructure with progressing *** recrystallized grains displayed characteristic orientations,such that their c-axes were perpendicular to the TD and additionally scattered between 0°and 60°from the loading *** recrystallized grains displayed mutual rotations of up to 30°around the c-axes of the initial grains,forming a discernible basal fiber texture component,prominently visible in the{1120}pole *** is noteworthy that the deformation and DRX behaviors of the two analyzed bicrystals exhibited marginal variations in response to strain and deformation temperature.

Journal of Materials Science & Technology 2008年第4期24卷 512-519页

作者： Yoshio BANDO dmitri GOLBERG Nanoscale World Premier International Center for Materials Nanoarchitectonics and Nanoscale Materials Center National Institute for Materials ScienceNamiki 1-1TsukbaIbaraki 305-0044Japan

In this review, the progress made during the last two years with respect to the syntheses and novel properties of one-dimensional （1D） ZnS nanostructures is presented. Primarily the research on 1D ZnS nanostructures has been of growing interest owing to their promising applications in nanoscale optoelectronic devices. Diverse 1D ZnS nanostructures with delicately-tuned morphologies, sizes, and microstructures have been synthesized through relatively simple and well-controlled techniques. Some novel properties of the nanomaterials have been explored and the relationships between their structural features and functions have been understood gradually.

Exotic pentaquarks as Gamov-Teller resonances

If the number of colors N c is taken large,baryons and their excitations can be considered in a mean-field *** argue that the mean field in baryons breaks spontaneously the spherical and SU（3） flavor symmetries,but retains the SU（2） symmetry of simultaneous rotations in space and *** one-quark and quark-hole excitations in the mean field,together with the SU（3） rotational bands about them determine the spectrum of baryon resonances,which turns out to be in good accordance with reality when one puts N c =3.A by-product of this scheme is a confirmation of the light pentaquark Θ ＋ baryon uudds as a typical Gamov–Teller resonance long known in nuclear *** extension of the same large-N c logic to charmed baryons leads to a prediction of a anti-decapenta （15）-plet of charmed pentaquarks,two of which,B ＋＋ c = cuuds and B ＋ c = cudds,may be light and stable with respect to strong decays.
