A tool to observe nanoscale deformation by transmission Kikuchi diffraction: This project seeks to establish an advanced in-situ characterisation capability for understanding the nanoscale processes that govern the properties of materials and how microstructures change during straining. A custom-designed mechanical straining device will operate within a scanning electron microscope configured for orientation mapping with the new technique of transmission Kikuchi diffraction. The facility, which would be the first in the world, is designed to have a very high spatial structural resolution of only a few nanometres for crystal orientation mapping and can be operated at temperatures up to 400 °C. The resulting knowledge may provide guidance for the design of structural materials and materials processing with applications in aerospace, transportation and medical devices.

通过透射菊池衍射观察纳米级变形的工具： 该项目旨在建立先进的原位表征能力，以了解管理材料特性的纳米级过程以及应变过程中微观结构如何变化。一个定制设计的机械应变装置将在扫描电子显微镜内操作，该显微镜配置为利用透射菊池衍射的新技术进行取向映射。该设施将是世界上第一个，其设计具有非常高的空间结构分辨率，仅为几纳米，可用于晶体取向映射，并可在高达400 °C的温度下运行。由此产生的知识可以为结构材料的设计和材料加工提供指导，并应用于航空航天，交通运输和医疗器械。
