Abstract

The evolution of structure property along the fission path in the superheavy nucleus $^{256}$Sg is predicted through the multi-dimensional potential-energy(or Routhian)-surface calculations,in which the phenomenological deformed Woods-Saxon potential is adopted. Calculated nuclear deformations and fission barriers for $^{256}_{106}$Sg$_{150}$ and its neighbors, e.g., $^{258,260}$Sg, $^{254}$Rf and $^{252}$No are presented and compared with other theoretical results. A series of energy maps and curves are provided and used to evaluate the corresponding shape-instability properties, especially in the directions of triaxial $\gamma$ and different hexadecapole deformations (e.g., $\alpha_{40}$, $\alpha_{42}$ and $\alpha_{44}$). It is found that the triaxial deformation may help the nucleus bypass the first fission-barrier of the axial case. After the first minimum in the nuclear energy surface, the fission pathway of the nucleus can be affected by $\gamma$ and hexadecapole deformation degrees of freedom. In addition, microscopic single-particle structure, pairing and Coriolis effects are briefly investigated and discussed., Comment: 26 pages, 10 figures

Abstract

With the rapid development of science and technology, wheel hubs of automobile are also developing towards lightweight and convenient. Aluminum alloys are increasingly used in wheel hubs due to their excellent performance, but the corrosion of aluminum alloy wheel hubs is still a big problem. This work briefly introduced several common corrosion types of aluminum alloy wheel hubs (filiform corrosion, pitting corrosion, grain boundary corrosion, stress corrosion, peeling corrosion). The influence of atmospheric environmental factors on the corrosion of aluminum alloy wheel hubs was introduced. Furthermore, the corrosion of different types of aluminum alloys in typical atmospheric environments at home and abroad, and the anti-corrosion methods of substrate modification and surface treatment for aluminum alloy wheel hubs were described.
