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.

通过传播kikuchi衍射观察纳米级变形的工具： 该项目旨在建立一个先进的原位表征能力，以理解控制材料特性的纳米级过程以及在应变过程中微观结构的变化。定制设计的机械拉力设备将在扫描电子显微镜中运行，该扫描电子显微镜配置了用于定向映射的新技术，该技术是通过新的传输Kikuchi衍射技术进行的。该设施将是世界上第一个的设施，其设计仅具有很高的空间结构分辨率，仅用于几纳米用于晶体方向映射，并且可以在高达400°C的温度下进行操作。所得的知识可能会为设计结构材料和材料加工的设计提供指导，并在航空航天，运输和医疗设备中应用。
