Investigation and Simulation on Amorphous Formation and Growth


Article Preview

The amorphous formation mechanism was studied from the viewpoint of the crystallography. The experimental results showed that the heterogeneity atoms with chemical bonds had a higher capability of forming into compounds than that of congener atoms. It was proposed that the banded structure was induced by the variation of active atoms with a proper thickness, alternated depletion and enrichment of anions in the diffusion layer due to generation and evolution of hydrogen gas. The chemical force plays an important part in the formation. The factors working on chemical reaction affect the formation in the same. A number of steady motes are in a high speed movement, and collide with each other in all probability. The formation of amorphous alloys is the result of massive nucleus appearance, which was proposed from the crystallography in this paper. The cause of the chaotic distribution is of the suppression of each nucleus growth. The short-range order atomic structure is of the atomic nucleus growth orientation. And the long-range disorder structure is of the massive nucleus suppression growth.
