Because the driving force of microstructural evolution for single-phase systems stems from the decrease of interfacial energy, so the second-phase particles will locate on the grain boundaries. The sites of second-phase precipitates on the grain boundaries can be determined by the fact that the steadiest system has the lowest systemic energy. Thus, that the spherical particles occupy usually the cross sites of triple grains and the stick particles arrange along with the grain boundaries is preferential, because this will result in the lowest systemic energy by providing least grain boundaries area. ×ÔÎҸоõ·ÒëµÄ²»´í |
