Introduction Synchrotron X-ray topography (SXRT) is a non-destructive technique that images structural defects (dislocations, stacking faults, grain boundaries, etc.) in bulk crystals, epitaxial films and wafers fabricated for electronic devices [1-5].

Thus, during the Portland cement clinker minerals hydration, a wide range of neoplasms are formed, and during the hardening of silicate materials based on aluminosilicate raw materials and lime under non-autoclave conditions, a limited number of types of neoplasms are formed [14-15] in the system CaO-SiO2(Al2O3)-H2O.

The method of combination large deformation meets the study of supersteel and ultrafine grained steel[7].
In order to develop new kinds of steel such as surface treatment strip steel, stainless steel that owns well performance, electric steel Fig.3 straight-pull reversing cold strip mill etc., we need to adopt different annealing treatment for sheet and strip, this need many kinds of theory research and large number of experiments.

Arrays of parallel layered surfaces are observed in the SEM picture (Fig.4a) for the film deposited at a solution pH 1.5 Small pores are also observed on the surface and fine grains are not observed in the micrograph.
Co-Ni alloy film prepared at solution pH 3.5 (Fig.4b) reveals comparatively a smooth surface and the number of pores is found to be reduced.

Introduction Magnesium alloys, due to their low densities and good casting properties, are attractive materials for use in certain machine housings, automotive, aerospace, and a number of other applications.
SEM observation and EDS analysis of debris removed from the composite sample (Fig.14) revealed the presence of very fine grained GCp surrounded with metal or oxide molecules.

One of the main contributors to poor removal rates for the colloidal silica CMP process is its tendency to selectively etch defects, grain boundaries and scratches.

Projects such as the European Extremely Large Telescope provide a relevant case study, where significant numbers of high-value bespoke optics are required.
Photomicrograph images of grains, and particle-size distributions from image-analysis, are presented in Figs. 4 and 5 respectively, and confirm a tail long-wards of the peak, which will influence texture.
