X-ray diffraction (XRD) technique was adopted to test the mineral composition of quicklime-solidified loess with different lime-adding rates at curing periods. Scanning electron microscopy (SEM) and nitrogen adsorption were used analyze microporous structure solidified loess. The unconfined compressive strength limit moisture content combined evolution mechanism microstructure change period cla...

Heat-resistant austenitic stainless steels are widely used in the final stages of superheater and reheater new generation fossil fuel power stations, due to their high creep strength. Similar weld joints, fabricated using gas tungsten arc welding, for connecting different components made heat resistant usually suffer from premature failures at elevated temperature [1]. Experimental studies show...

Traditional fracture theories infer damage at cracks (local field) by surveying loading conditions away from (far field). This approach has been successful in predicting ductile fracture, but it normally assumes isotropic and homogeneous materials. However, myriads of manufacturing procedures induce heterogeneous microstructural gradients that can affect the accuracy traditional models. work pr...

Al2O3-YAG-ZrO2 eutectic ceramic rods of 5 mm in diameter were grown by micro-pulling down technique. The seeding and the solidification rate affect microstructure, morphology, crystallography, thermal stress solidified ceramics. ternary through zirconia (111) seed had inhomogeneous irregular cellular microstructures. At stationary stable regime, microstructure spacing (λ) depends on pulling (v)...

the crystal structure of the title schiff base complex is obtained by single-crystal x-ray diffraction data.the solid state structure determination reveals that the coordination geometry around the copper(ii) center istetrahedrally distorted square-planar. the crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.
