3 The chemical bonding at a grain boundary of an Fe-doped SrTiO bicrystal has been determined by combination spatially resolved electron energy-loss spectroscopy and first-principles molecular-orbital calculation. near-edge structure the O K-edge spectrum on shows that manner TiO linkage is different from in bulk . changes 6 locally corner-sharing to edge-sharing configuration same time as 2 removal Sr ions boundary. This type theoretical calculation demonstrated be powerful tool for...
(NH4)2SO4 roasting–water leaching process was studied as a method for improving the utilization efficiency of magnesite. Transformation mineral phases during roasting evaluated by X-ray diffraction (XRD) analysis, combined with thermogravimetry−differential thermal analysis (TG−DTA). The data were compared phase transformation MgO using (NH4)2SO4. experimental results demonstrated that at (NH4)2SO4/ magnesite (MgO in ore) molar ratio 1.6:1, temperature 475 °C, and time 2 h particle size ~74...
The S phase (Al 2 CuMg) is an important strengthening for the Al–Cu–Mg alloys, which are widely used in aerospace and transportation industries. commonly added alloying elements (Mn, Ti, Zr) impurity (Fe Si) alloys always found phase. First-principles calculations based on density functional theory (DFT) were to investigate influence of doping Mn, Zr, Fe Si Key findings demonstrated that these prefer occupy different atomic sites Ti Zr improved structural stability bulk modulus Fe, Si, doped...
The rapid development of communication technology and computer networks has brought a lot convenience to production life, but it also increases the security problem. Information become one severe challenges faced by people in digital age. Currently, problems facing field China mainly include evolution offensive technology, risk large-scale data transmission, potential vulnerabilities introduced emerging dilemma user identity verification. This paper analyzes frontier network security, puts...
In this study, the in-situ fatigue crack observation is carried out for three kinds of wheel steels. The results show that mainly propagates along ferrite materials with thick and continuous network. probability meandering at grain boundary larger than pearlite colony. For thin discontinuous network, however, can propagate into across boundary. occurs colony values growth free path be approximatively represented by austenite size these two types materials, respectively.
