| 中文摘要 | The as yet unresolved microstructure of the periodic layers formed in the reactive diffusion system Mg/SiO(2) was clarified by using high-resolution field-emission SEM. The periodic layered structure actually consists of the single-phase layer of Mg(2)Si and the two-phase layer of (Mg(2)Si + MgO) alternated within the reaction zone. According to the experimental observations and in line with the diffusion-induced stresses model, the mechanism controlling this phenomenon could be attributed to the stresses induced by the difference in interface growth rates of Mg(2)Si and MgO phases within the layer. When the elastic deformation of the slow-growing aggregated-MgO phase reaches its elastic maximum, it will be split off from the reaction front by the neighboring Mg(2)Si phase and a new periodic layer forms. The computer simulation results are coinciding well with the experimental data. (C) 2009 Elsevier Ltd. All rights reserved. |
