EBSD 2021

20 – 21 April 2021
The University of Sheffield
Meeting
+ Add to calendar


Scientific Organisers: Prof Brad Wynne, University of Strathclyde and Dr Dikai Guan, University of Sheffield

The EBSD meeting will take place at The Edge, Endcliffe Village, The University of Sheffield. The annual gathering draws together the whole Electron Backscatter Diffraction (EBSD) community, including leading international research scientists and engineers, early career researchers, and students to highlight the latest developments, from technique development through to applications.

We are anticipating contributions that range in scope spanning the geoscience, materials science & engineering, and mechanical engineering disciplines, as well as emerging applications from the biological communities. Talks will likely include state-of-the-art developments in instrumentation, new software algorithms, and new techniques developments, as well as the use of EBSD, transmission Kikuchi diffraction, electron channelling contrast imaging (ECCI) and related microscopy modalities. Additionally, we anticipate hearing applications driven talks which engage these approaches to reveal new insight into the microstructure of materials systems in emerging scientific applications and industrial challenges, particularly the use of EBSD data in Industry 4.0.

The meeting will be preceded on Monday 19 April, by one of two optional workshops, for both advanced and novice users. The advanced course, delivered by Prof João Fonseca’s group at the University of Manchester, focusses on the use and understanding of High-Resolution Digital Image Correlation (HRDIC) combined with EBSD, centred on technical requirements and the underlying principles of post-processing data analysis. The novice course, delivered by Prof Brad Wynne, focusses on understanding what is under the hood of your EBSD software, with particular emphasis on maximising the potential of your EBSD data both before acquiring your data and during its analysis.  For further details please visit the Pre-Meeting Workshop tab.


Invited Speakers

Quantifying plastic deformation in metallic microstructures using EBSD and High Resolution Digital Image Correlation

  • Prof João Quinta da Fonseca

    University of Manchester
    Professor João Fonseca did his PhD on the mechanical behaviour of high volume fraction MMCs at the University of Leeds, before moving to the University of Manchester, where he worked on developing algorithms for digital image correlation and on using crystal plasticity modelling to simulate in-situ diffraction deformation experiments. He is now Professor of Mechanical Metallurgy, with special interest on the forming of light-weighting alloys and also does research on nuclear materials like Zr alloys and stainless steel, and on Ni superalloys for aeroengine applications. This research ranges over topics such as (micro-)experimental mechanics, computational crystal plasticity, crystallographic texture, recrystallisation and phase transformations.
     

Characterising crystal defects in tungsten carbide using electron diffraction

  • Dr Vivian Tong

    National Physical Laboratory
    Vivian Tong is a Higher Research Scientist in the Materials Characterisation group at NPL. She develops EBSD data analysis methods to characterise microstructure and micro-scale deformation mechanisms, and to link EBSD to other types of microscopy data. She completed her PhD at Imperial College London in 2016, on using EBSD to understand heterogeneous deformation and recrystallisation in zirconium alloys.

HR-EBSD constraints on the role of dislocations and their stress fields in transient creep of Earth’s upper mantle

  • Dr David Wallis

    Utrecht University 
    I am a structural geologist focusing on the materials science of rock deformation. I completed my PhD at the University of Leeds in 2010 and undertook a postdoc at the University of Oxford before becoming an Assistant Professor at Utrecht University in 2017. My research is centred on using HR-EBSD to map dislocations and their stress fields in deformed minerals and decipher their role in controlling the rheological properties of rocks at high temperatures.
     


Scientific Organisers

  • Prof Brad Wynne

    University of Strathclyde
    Prof Brad Wynne is Research Director at the Advanced Forming Research Centre at the University of Strathclyde as well as a member of staff in the Department of Mechanical and Aerospace Engineering. He has extensive experience in both experimental EBSD data acquisition and development of bespoke code for its analysis. Example codes include beta reconstruction code and macrozone analysis tools for titanium alloys, both of which are used extensively in academia and industry.
     

  • Dr Dikai Guan

    University of Sheffield
    Dr Dikai Guan is Electron Microscope Research Experimental Officer at the [email protected] in the Department of Materials Science and Engineering. He has significant expertise in using conventional EBSD and developing advanced EBSD for data acquisition and analysis. The quasi-in-situ EBSD method, as well as newly developed TKD and HR-EBSD, have been widely used in the department for a wide range of materials.
     


Monday Workshop

On Monday 19 April we will be running two parallel afternoon workshops.  It will start at 12.45.  In order to attend  a workshop you need to be registered to attend the two day meeting taking place on Tuesday  20 and Wednesday 21 April.

Novice Workshop:  What is under the hood and your EBSD software? What does the data all mean?

EBSD is now a well-established technique in a wide range of disciplines in both the research and industrial environments. In fact, EBSD orientation image maps or pole figures are now, in many cases, standard reporting items for release on product delivery. However, to the new user EBSD can look like pretty pictures, be it in an orientation image map or pole figure, and not the rich datasets they are. In this workshop, we take a look under the hood of your EBSD dataset and the software used to analyse it to explain the fundamentals of your data and how it is presented. Using simple code examples, we will explain how a map and pole figure are constructed, including identifying boundaries, etc. Furthermore, the workshop will explain to you how to maximise the data you get, both before undertaking data acquisition and during its analysis.  

Prof Brad Wynne will lead this workshop. Brad has been working on developing code for EBSD analysis for over 20 years, with many examples currently being used in both academia and industry.

Advanced Workshop:  High Resolution Digital Image Correlation combined with EBSD – technique and data analysis

The High Resolution Digital Image Correlation (HRDIC) technique has opened up quantification of heterogeneous displacements within materials, including those from induced by applied load and phase transformations. In principle, the measurement of local shear strain enables one to assess and compare the true level of strain heterogeneity for different alloy chemistries, microstructures and the effect of microstructure inhomogeneity. In addition, recording the shear strain associated with slip traces and combining this information with EBSD-based orientation imaging enables one now to undertake truly quantitative slip trace analysis.

In this workshop the basic principles of the gold remodelling technique for applying a speckle pattern to the surface of a material for obtaining HRDIC data in an SEM is presented. This is followed by a detailed description of the software and its use to obtain the displacement analysis and subsequent post processing and how this data is combined with EBSD analysis. Finally some worked examples will be presented.  

Prof João Fonseca’s group at the University of Manchester will lead this workshop.
