| 中文摘要 | 基于电子背散射分析(EBSD)技术对纯铜柱状晶标定获得的初始晶粒形貌和平均取向,利用晶体塑性理论,建立了基于晶粒真实取向和形貌的多晶塑性有限元模型,模拟了纯铜柱状晶单轴压缩过程中的取向变化,并对形变带形貌进行初步模拟.通过相应的单轴压缩实验获得了取向变化和形变带形貌的实验数据.系统地比较了多晶样品中各晶粒取向演化和形变带形貌的模拟结果和实验结果,得到晶粒取向和微观结构变化的统计性结果.; The initial morphology and mean orientation of columnar-grains of pure copper are obtained by electron backscattering diffraction(EBSD).A finite element model based on crystal plas- ticity was established to simulate the orientation and deformation band evolutions of individual grain during uniaxial compression.Corresponding compression test was carried out to obtain experimental data which showed the actual evolutions of orientation and band morphology in the polycrystalline sample.A series of statistical results of grain orientation evolution were obtained,and the calculated results were compared to experimental data.; 国家自然科学基金50575124 |
