| 摘 要： | 采用了周期性边界条件及各向同性的动力学相场模型研究了场变量参数对二维多晶生长的影响.模拟结果表明:场变量数目的多少对晶粒生长的规律没有显著影响:即二次幂规律,场变量数目越大,晶粒合并的几率越小,生长越慢.同时又对不同场变量下晶粒的相对尺寸分布进行了研究,结果显示晶粒的相对尺寸分布形式具有相似性.

| Abstract: | Supported by Science Research Project of educational department of Liaoning province goverment(No.05LA15),the effect of phase field model with different orientation field variables on 2D grain growth was investigated,in which the periodic boundary conditions and isotropy dynamics were applied.The simulated results reveal that the grain growth appears to be a quadric power law,and there are little effects of the variation of the number of field variables on the grain growth law.The more the number of orientation field variables are,the little the probability of the grain coalescence is,and the more slowly the grains grow.The grain size distribution for different orientation field variables also was studied.The result shows the distribution has self-similarity. |
