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.
