About Cover

The cover photo describes the ring topological structure of carbon nucleus (using vortex-fractal-ring theory), which consists from two globules with 3 protons globule substructures. As discussed by, this vortex-fractal-ring theory is a new and original view of elementary particles and the structure of atomic nuclei, atoms, and molecules. Its basics are simple for understanding through the comprehensive topological structure that does not need description by complicated mathematical formulas. This theory together with grammatical evolution can design new models of nanostructures and allows us to understand the fundamental physical and chemical reasons for the stability and reactivity of atoms and molecules.

Abstract

The microstructure evolution in a Fe-Cu alloy with/without pre-deformation during the aging treatment is investigated numerically. The results demonstrate that although the Cu precipitates first nucleate on dislocations, the summit of the nucleation rate occurs in the matrix. Most of Cu particles situate in the matrix immediately after the nucleation. The preferential dissolution of Cu precipitates in the matrix occurs during the Ostwald repining stage, and the vast majority of the residual particles situate on dislocations in an overaged alloy.
