本研究利用康奈尔高能同步加速器的x射线衍射设备,对大角度晶界的结构进行了研究。根据x射线衍射结果和模型确定晶界的原子结构。研究内容包括杂质在扭转晶界的偏析和晶界的热性能。该程序为精确的晶界模型提供了重要的、高质量的数据,并提供了由于成分或温度变化而引起的晶界结构变化的基本知识。
英文摘要
This research examines the structure of large angle grain boundaries using the X-ray diffraction facility at the Cornell High Energy Synchrotron Source. Atomic structure of grain boundaries is determined based on the X-ray diffraction results and modeling. The research includes a study of impurity segregation to twist boundaries and the thermal properties of grain boundaries. The program provides important, high quality data needed for accurate models of grain boundaries and gives fundamental knowledge concerning grain boundary structure shifts due to composition or temperature changes.
