RMS EBSD 2020 UK April 21st-22nd Cancelled

Due to the Coronavirus-19 pandemic, this year’s RMS EBSD conference has been cancelled. We look forward to seeing everyone again in 2021 and wish all our users, colleagues, families and fellow scientists our best wishes and please, stay safe.



The Path To Absolute (HR) Strain Measurement

Read about the current state of the art in the field of absolute strain measurement, the use of simulated EBSD patterns and the work underway here at BLG Vantage.

Latest NIST publication on HR EBSD

NIST have recently published an excellent paper on how HR-EBSD can improve critical spacial resolution and sensitivity issues when measuring strain.

Screen Shot 2019-05-03 at 9.05.20 PMAbstract: Compared to more commonly used strain measurement techniques, electron backscatter diffraction (EBSD) offers improved spatial resolution and measurement sensitivity. Additionally, EBSD can provide the full deformation tensor, whereas other techniques, such as digital image correlation (DIC), are lim- ited to only in-plane strains and rotations. In this work, EBSD was used to measure strains and rotationsin-situ during testing of a single-crystal silicon micromechanical test specimen. The theta-like specimen geometry was chosen due to the complex and spatially-varying strain states that exist in the circular frame of the sample during testing, as well as the nominally uniform strains in the central web. Full-field strain maps were generated for each strain and rotation component and compared to those from finite element analyses (FEA), showing strong agreement in all cases. Additionally, potential sources of error and their impact on both measurement accuracy and uncertainty are discussed.  Read more here.

We have recently uncovered some archive footage from 1987 of David Dingley and the Physics EM Group at Bristol University, UK demonstrating the first semi-automated indexing system. You can find it on our YouTube HR EBSD channel together with Part 1 and Part 2 of David Dingley’s presentation to the ICOTOM 18 audience in St George, Utah, USA. Part 1 (of 3) takes us through the early days of automated EBSD data collection and orientation indexing and the evolution of HR EBSD. Part 2 illustrates some nice applications of the HR EBSD technique using CrossCourt and finally Part 3 (pending) takes us through latest advances in the technique and recent activity here at BLG Vantage. Enjoy!
