這是因為單相多晶系統(tǒng)晶粒演化的驅(qū)動力來源于系統(tǒng)界面能的減少，第二相粒子位于晶界上使界面能降低，所以當圓形第二相粒子占據(jù)三晶交叉處，棒狀第二相粒子位于晶界且方向與晶界方向一致時，系統(tǒng)中的晶界面積減少最多，系統(tǒng)中界面能最小，這符合系統(tǒng)的演化趨勢。 附專業(yè)詞匯： 圓形第二相粒子 spherical second-phase particles 棒狀第二相粒子 stick second-phase particles 界面能 interfacial energy 晶界 grain boundary |

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. 自我感覺翻譯的不錯 |

| This is because the single-phase evolution of polycrystalline system, the driving force of grain from the system interface can be reduced, and the second phase particles at grain boundaries can reduce the interface, so when the circular second phase particles occupy the intersection of the three crystals, rod-like second-phase particles in the direction of the grain boundary and grain boundary in the same direction, the system reduces the size of the largest grain boundaries, the system interface to the minimum, consistent with trends in the evolution of the system. |

真理的出現(xiàn)不在于早或晚！樓主千萬別錯過呦 Due to the reduction of the interfacial energy, from which the driving force of the grain evolution in monophase multicrystal system is originated, and the particle from the second phase locating on the boundary surface enable the lowering of interfacial energy, the area of the grain boundary and the interfacial energy reduce to a minimumvalue when the round/sperical second-phase particle occupy the trimorphous intersection, whereas the bar-shaped/stick second-phase particle locate on the boundary surface with their orientation parallel to the boundary. It is in accordance with the tendency for the system to evolve. [ Last edited by noleg on 2010-6-11 at 21:37 ] |
