Discovering Materials with Electron Backscatter Diffraction (EBSD)

Abstract:

The way a material’s atoms arrange themselves - its crystalline structure - plays a crucial role in determining its properties. This ordering can span an incredible range of length scales, from nanometers to millimeters. In this talk, I will introduce one powerful method for probing these structures in two and three dimensions: electron backscatter diffraction (EBSD), a versatile technique within the scanning electron microscope. After a brief overview of how EBSD works, I will showcase recent advances and applications that demonstrate its value in tackling diverse materials challenges, such as three-dimensional mapping of engineering alloys, analyzing two-dimensional materials, and characterizing minerals and ceramics. To wrap up, I will share some of the exciting new electron diffraction capabilities now available - and soon to arrive - at UBC, expanding what we can learn about the structure and behavior of complex materials.

Dr. Ben Britton is a Professor in the Department of Materials Engineering, Faculty of Applied Science at UBC. He heads the “Experimental Micromechanics and Characterization” Group, where his team develops new ways to analyze and understand the mechanical behavior of engineering materials, especially metals and ceramics. Electron backscatter diffraction continues to be a core theme of Dr Britton’s work, with contributions that include new software, hardware, experimental approaches, and applications. These are often intertwined with correlative approaches, new forms of microanalysis, and advancing manufacturing methods of materials. He leads and collaborates on multiple research projects at UBC, including the Characterization @ UBC GCRC cluster, and plays a key role in guiding electron microscopy activities at the EMLab within the Department of Materials Engineering.
