Implementation of HR-EBSD and ECCI for advanced microstructure analyses on the nanoscale

In order to achieve breakthroughs in the understanding and development of materials, new and advanced analysis methods are crucial. Especially, looking at the µm to atomic scale, which is still challenging, helps to understand fundamental mechanisms behind macroscopic phenomena. This understanding, in turn, can help to improve manufacturing processes and in the design of new materials. In this project, new and advanced SEM analysis methods namely Electron Channelling Contrast Imaging (ECCI) and High Resolution Electron Backscatter Diffraction (HR-EBSD) should be established at the University of British Columbia (UBC). Moreover, the limits of these methods in terms of resolution should be tested and advanced. The results will be crosschecked by means of Transmission Electron Microscopy (TEM) at the NRC Nanotechnology lab in Alberta. Both methods can be used to understand deformation processes better and to visualize defect structures in various materials (metals, minerals and ceramics).For this project, we will develop the approach to look at electrical iron silicon steel, which is the core of every electric machine, where it guides and magnifies the magnetic flow. Optimising the performance of this material is critical to maximise energy transmission efficiency and reduced losses.
