The grain refinement and its effect on the mechanical properties of AZ31 magnesium alloys were investigated. The grain refinement was conducted using one of the severe plastic deformation methods, warm constrained groove pressing (CGP) technology. The eff... see more

Pure calcium silicate hydrate – gyrolite was prepared under the saturated steam pressure at 473 K temperature in rotating autoclave. The crystal structure of synthetic gyrolite was investigated by X-ray diffraction and refined using Le Bail, Rietveld and ... see more

The several simulated X-ray diffraction patterns for calcium silicate hydrate – gyrolite were calculated with GSAS program using the structural model of natural mineral gyrolite and profile parameters values determined from refining crystal structure of r... see more

The theoretical capabilities and practical recommendations of increasing the both an accuracy of coordinate estimation and reliability of  ballistic and space targets classification by using estimates of range higher order derivatives for surveillanc... see more

Large eddy simulation of turbulent channel flow is carried out at Ret values of 150 and 395. Mesh refinement effects are evaluated on conventional meshes, then local mesh refinement in streamwise direction is applied and investigated. The goal of the pape... see more

The Rietveld method is the most reliable and powerful tool for refining crystal structure when powder diffraction data are available. It requires that the structure model to be adjusted is as close as possible to the true structure. The Rietveld method us... see more

Precipitates in thin-walled (11 mm) and thick-walled X70 (17 mm) microalloyed X70 pipe steel are characterized using Rietveld refinement (a.k.a. quantitative X-ray diffraction (QXRD)), inductively coupled plasma mass spectrometry (ICP), and energy-dispers... see more

With the rapid development of urban transportation, people urgently need high-precision and up-to-date road maps. At the same time, people themselves are an important source of road information for detailed map construction, as they can detect real-world ... see more
