Insights into magmatic processes from the crystal orientation mapping of igneous microstructures
… processes that remain poorly understood. Mapping crystallographic orientations using electron backscatter diffraction (EBSD) has revolutionised the study of deformed rocks, and is now emerging as a useful tool for studying igneous rocks. In this thesis, I combine EBSD with field, …

Methods and Applications for Nanometrology using Scanning Precession Electron Diffraction
… improvement for two key areas within the field - orientation mapping and strain mapping - are demonstrated, allowing for significant increases in both throughput and accuracy. Comparisons are made between different electron-based techniques including the extremely popular electron backscatter …

Low-Temperature Gas-Phase Nitriding and Nitrocarburizing of 316L Austenitic Stainless Steel
… of nitrogen-enriched expanded austenite.</p><p>Orientation-dependent nitrogen surface concentration and case depth were investigated using EBSD orientation mapping and AES cross-sectional line scans. In particular, <100>-oriented grains demonstrated a higher surface nitrogen concentration and a …

Characterizing Plastic Deformation Mechanisms in Metal Thin Films using In Situ Transmission Electron Microscopy Nanomechanics
… migration. This is completed by combining orientation mapping with in situ TEM straining to document the stress-induced migration behavior across boundaries of different structure.

Quantitative analysis of crystal lattice and defects in nanoscale functional materials by electron diffraction
… and versatile technique for lattice strain mapping using SEND. The measurement of strain is based on determining the Bragg peak positions recorded in the diffraction patterns from a local crystal volume. To address the issue of peak broadening from a focused electron probe, we propose a new …

Dry sliding wear of metals: From subsurface microstructure to tribological behavior
… the wear resistance of the CuNiSn bronze. Orientation imaging microscopy was employed to analyze the severely deformed layer produced in Cu-15Ni-8Sn bronze and Ni pins by dry sliding wear under various loads and temperatures. In all cases, a nanograined layer that possesses significant …
