Acta Metallurgica Sinica(English Letters) 2014年第6期27卷 1088-1098页

Nanocrystalline and amorphous Mg2Ni-type（Mg24Ni10Cu2）100–xNdx（x = 0, 5, 10, 15, 20） alloys were prepared by melt-spinning technology. The structures of as-cast and spun alloys were characterised by X-ray diffraction,scanning electron microscopy and transmission electron microscopy. Electrochemical performance of the alloy electrodes was measured using an automatic galvanostatic system. The electrochemical impedance spectra and Tafel polarisation curves of the alloy electrodes were plotted using an electrochemical work station. The hydrogen diffusion coefficients were calculated using the potential step method. Results indicate that all the as-cast alloys present a multiphase structure with Mg2 Ni type as the major phase with Mg6 Ni, Nd5Mg41 and Nd Ni as secondary phases. The secondary phases increased with the increasing Nd content. The as-spun Nd-free alloy exhibited nanocrystalline structure, whereas the as-spun Nd-doped alloys exhibited nanocrystalline and amorphous structures. These results suggest that adding Nd facilitates glass formation of Mg2Ni-type alloys. Melt spinning and Nd addition improved alloy electrochemical performance, which includes discharge potential characteristics, discharge capacity, electrochemical cycle stability and high-rate discharge ability.

Improved Hydrogen Storage Kinetics of Nanocrystalline and Amorphous Mg-Nd-Ni-Cubased Mg_2Ni-type Alloys by Adding Nd

引用

Journal of Wuhan University of Technology(Materials Science) 2015年第6期30卷 1115-1124页

作者：张羊换 ZHAI Tingting YANG Tai YUAN Zeming ZHANG Guofang DONG Xiaoping Key Laboratory of Integrated Exploitation of Baiyun Obo Multi-Metal Resources Inner Mongolia University of Science and Technology Department of Functional Material Research Central Iron and Steel Research Institute College of Quality and Technical supervision Hebei University

In order to improve the gaseous and electrochemical hydrogen storage kinetics of the M2Nitype alloy, the elements Cu and Nd were added in the alloy. The nanocrystalline and amorphous Mg2Ni-type alloys with the composition of（Mg24Ni10Cu2）100-xNdx（x = 0, 5, 10, 15, 20） were prepared by melt spinning technology. The effects of Nd content on the structures and hydrogen storage kinetics of the alloys were investigated. The characterization by X-ray diffraction（XRD）, transmission electron microscopy（TEM） and scanning electron microscopy（SEM） reveals that all the as-cast alloys hold multiphase structures, containing Mg2Ni-type major phase as well as some secondary phases Mg6Ni, Nd5Mg41, and Nd Ni, whose amounts clearly grow with increasing Nd content. Furthermore, the as-spun Nd-free alloy displays an entire nanocrystalline structure, whereas the as-spun Nd-added alloys hold a mixed structure of nanocrystalline and amorphous structure and the amorphization degree of the alloys visibly increases with the rising of the Nd content, suggesting that the addition of Nd facilitates the glass forming in the Mg2Ni-type alloy. The measurement of the hydrogen storage kinetics indicates that the addition of Nd significantly improves the gaseous and electrochemical hydrogen storage kinetics of the alloys. The addition of Nd enhances the diffusion ability of hydrogen atoms in the alloy, but it impairs the charge-transfer reaction on the surface of the alloy electrode, which makes the high rate discharge ability（HRD） of the alloy electrode fi rst mount up and then go down with the growing of Nd content.

The aim of this study was to determine the frequency of infectious diseases among people entering/exiting via Manzhouli port. We analyzed infectious disease data from the Manzhouli International Travel health care Center covering 2012 through 2014, as well as performed several laboratory tests to measure rates of infection. The frequencies of infectious diseases as well as their association with occupation and year of occurrence were calculated for people entering and exiting via the port. The total proportion of infectious diseases measured was 2.18%. Hepatitis B was the most commonly occurring at 1.68%, followed by syphilis, hepatits C and HIV, which were 0.23%, 0.21% and 0.04%, respectively. Contract workers, traffic staff, foreigners and those married abroad were more likely to be infected. Furthermore, there were significant differences among three years. Strategies should be developed and preventive policies should be implemented aimed at protecting the at risk populations at Manzhouli port, especially with regard to contract workers, traffic staff, foreigners and those married abroad.

To systematically validate and calibrate the theory and technology of the deep in-situ conditionpreserved coring, the in-situ conditions at different depths should be simulated, and the full-size coring tests should be carried out in this simulated environment. Therefore, a deep-rock in-situ conditionpreserved coring calibration platform was designed and developed. The self-tightening sealing structure and the quick-disassembly structure were designed on the basis of an innovative segmented nonuniformdiameter structure, which was a breakthrough from the traditional high-pressure vessel frame and was verified by finite element simulation and actual testing under extreme working conditions, *** simulate the actual deep in-situ environment with a temperature of 150℃ and pressure of 140 MPa for a large Φ450 mm×H1400 mm core, temperature and pressure control systems were designed by coupling, and a pre-embedded high-pressure-resistant temperature sensor was designed. Finally, highprecision assembly automation, complex movement coordination of the coring device with the platform,and rotary dynamic sealing were achieved by utilizing the combination of adaptive cabin body servo control and an adaptive mechanical structure in a limited space, laying a solid foundation for the calibration of in-situ condition-preserved coring.
