3. Cu-Al-Ni wires with columnar grain structure fab- ricated by heated mold continuous casting process were con- ducted bending fatigue and tensile fatigue tests to study the behavior of grain boundaries in fatigue process. 用热型连铸法制取具有柱状晶组织的Cu-Al-Ni合金丝,进行弯曲疲劳和拉伸疲...
The crystal structure of Kuzel's salt has been successfully determined by synchrotron powder diffraction. It crystallizes in the rhombohedral R3 symmetry with a = 5.7508 (2) A, c = 50.418 (3) A, V = 1444.04 (11) A~3. Joint Rietveld refinement was realized using three X-ray powder patte...

For the former structure it was found that the spacing of (110) plane varies with the position in a particle. The latter structure has modulation along the four-fold rotational axis and is considered to have a structural relation to the tetragonal Al m Fe structure. The Fe concentrations in...
Such an approach provides predicted values of crystal-field parameters, Zeeman splitting g-factor, and hyperfine structure constants. Moreover, the C-3v site symmetry is found to be a good approximation for the actual C-3 site of Yb3+, as doped in an alpha-Al2O3 crystal. 展开 ...
