请英语高手帮忙翻译摘要，尽量要翻译专业一点！非常感谢！！ 摘要：采用相场方法，模拟了第二相粒子的取向和形态对基体晶粒长大的影响。模拟结果表明：在晶粒长大过程中，绝大部分圆形颗粒位于三晶交点处，棒形颗粒位于晶界处并与晶界方向一致，颗粒表现出强烈地钉扎晶界的作用，最终的平均晶粒半径可以用Zener关系表示；当面积分数和粒子尺寸一定时，棒状第二相颗粒钉扎晶界的效果好于球状第二相颗粒。 关键词：相场法模型；晶粒长大；第二相粒子；Zener钉扎 Abstract: Key words: phase-field method;grain growth;second-phase particles; Zener pining 附： 第二相粒子的取向和形态：the orientation and shape of second-phase particles [ Last edited by 小兰花 on 2009-9-25 at 12:06 ] |

particles on grain growth of a sample was simulated using the phase-field method. Simulation results show that most of the spherical particles sit at intersection points of three grains, and rodlike particles sit in between grain boundaries with their orientation parallel to the boundary during grain growing. All particles show strong grain boundary pinning effect. The average grain size can be expressed using the Zener relation. When keeping both area fractions and particle dimensions constant, The pinning effect of rodlike particles of the second -phase is better than that of the spherical particles of the second-phase.

| Using phase-field method ,the effect of matrix grain growth from the orientation and shape of second-phase particles was simulated. Simulation results show that,in the grain growth process, most of the round particles were in the intersection of three crystals, rod-like particles were at the grain boundaries in the same direction with the grain boundary, and grain showed a strong grain boundary pinning effect and the final average grain radius can be expressed by Zener relations; when the area fraction and particle size iwere constant, rod-like second-phase particles pinning the grain boundary effect is better than spherical second-phase particles. |

| The phase-field method was employed to simulate the effect of the orientation and shape of second-phase particles to the matrix grain growth. The results demonstrate that, during the grain growth, most of the round particles locate at the intersections of three crystals, rod-like particles lie at the grain boundaries, which is also in consistent with the direction of the grain boundary. All the particles exhibit strong grain boundary pinning effect and the final average grain size can be expressed by Zener relations; when the area fraction and particle size were constant, the grain boundary pinning effect of the rod-like second-phase particles is better than that of the spherical second-phase ones. |
