| 摘 要： | 基于高温X射线衍射实验,利用多域分理论研究了InCu熔体内原子簇在不同温下时空特性,表征了InCu金熔体几构特征.果显示,In,In-1wt.%CuIn-20wt.%Cu熔体构是种部分重叠多域分构,InIn-1wt.%Cu低维分维数随着温升高而升高,In-20wt.%Cu熔体低维分维数随着温升高出现不规则变化,且分维数可作为构敏感参数反映金构变化.In-57wt.%Cu熔体构也存在分特性,但不存在多域特性.利用多域分模,计算了In,In-1wt.%CuIn-20wt.%Cu熔体多域分过区域原子个数,由模计算所lnN-lnr曲线与实验所致,lnN-lnr曲线最大误差不超过1.22%,多域分范围熔体构有着对应联系,测多域分过区域与熔体构特性有关.利用超微粒聚制释了熔体分貌.

| Abstract: | Multirange fractal analysis based on results of high temperature X-ray diffraction experiment is used to study the geometric structure characteristics and temporal-spatial properties of clusters of InCu melt.The results show that partially-overlapping multirange fractal structure is observed in In,In-1wt.%Cu and In-20wt.%Cu melt and low-dimensional fractal dimensions of In and In-1wt.%Cu melt increase as temperature increases,while that of In-20wt.%Cu melt irregularly changes.Fractal dimension can be consid... |
