The X-ray diffraction spectra and X-ray photoelectron spectroscopy were measured for Sr-doped La1-xSrx CoO3 materials with perovskite structure prepared by the
The model of dislocations was used to construct the model of grain boundary (GB) with pure rare earths, and rare earth elements and impurities. The influence of
The influence of rare earths on the behavior of precipitation of 14MnNb,X60 and 10MnV steels was studied by STEM, XRD, ICP and thermal simulation method. The ma
By theoretical analysis of heat transfer during the "one-step" directional solidification process, the functional relation between the temperature in solid-liqu
