在这封信中，我们研究了离散移动位错对晶格不匹配二元合金中旋多分解动力学的影响。通过采用一种新的连续介质模型，我们证明了位错迁移率对区域粗化动力学的影响可以通过标度函数统一表达，描述了从t（1/2）到t（1/3）的交叉行为。(c) 2005年美国物理研究所。
In this letter, we examine the effects of discrete mobile dislocations on spinodal decomposition kinetics in lattice mismatched binary alloys. By employing a novel continuum model, we demonstrate that the effects of dislocation mobility on domain coarsening kinetics can be expressed in a unified manner through a scaling function, describing a crossover from t(1/2) to t(1/3) behavior.
