Study on the charge transference and local magnetic moment of yttrium-cobalt compound

The electronic charge transference and local magnetic moment of the YCo₅ intermetallic compound were calculated using SCF-MO-DVXα method and multiple cluster model. The result shows that about one 4d-electron is transferred from anY atom to Co₁(2c), and the calculated local spin magnetic moments of Co_I(2c) and Co_II(3g) atoms in YCo₅ compound are 1.33 and 1.48μ _B , respectively, which are in very good agreement with experiments.

Ab initio calculation of structure and Raman and Infrared spectra of Trifluoromethylthiosulphenyl Chloride

The molecular model of Trifluoromethylthiosulphenyl Chloride, CF₃SSCl, was presented.Ab initio method was used to calculate the structure and Raman and Infrared spectra. The results show that CF₃SSCl possess stereoscopic structure ofC ₁ symmetry with a torsional angle of 94.2°. The potential energy distribution and isotope replacement methods were applied to determine the vibrational assignment. The vibrational frequencies and corresponding modes of the molecule were obtained. The calculated vibrational frequencies are in good agreement with experiments.

Interface bond mechanisms of ceramic-cemented carbide compact insert

Conclusion Ceramic-cemented carbide compact inserts have been developed by hot-pressing sintering techniques, the upper part of the compact insert is of Al₂O₃ + TiB₂ ceramic material, while the base part of the compact insert is of WC + Co cemented carbide. The compact insert makes full use of the advantages of the high hardness of ceramic materials and the high strength of cemented carbide, and its mechanical properties are just between that of Al₂O₃ + TiB₂ and WC + Co. SEM, XRD and electron microprobe analysis showed that element diffusion and formation of new phases are the main causes for the bond of Al₂O₃ + TiB₂ with WC + Co in the interface.
