trace analysis

[Abdo M.]

I have an SEM and EBSD data. and I want to use the slope (defined by the slip inclination in obtained from SEM image) to use the EBSD data to get the slip plane and direction but the information on EBSD data are in Euler angles, and I am not sure about how to rotate from the sample to crystal frame (bcc). I wonder if someone is using a code that I can modify to fit my work.

Hi

Can you expand on how did you obtain your images and, what sort of SEM images they are and how do you plan to use them to define a slip system and slip direction? In principle what you want to do is only possible via Burgers vector analysis on TEM, but I may have missed something here

All the best

Hi

I am aiming to replicate the below paper’s work for trace analysis using MTEX.

EBSD-assisted slip trace analysis during in situ SEM mechanical testing: application to unravel grain size effects on plasticity of pure Mg polycrystals. https://doi.org/10.1007/s11837-015-1521-6 

Thanks,

you can rotate the slip plane by the grain mean orientation to sample coordinate, and then the observed slip plane trace will be the cross dot of two vectors (the slip plane normal and the observed plane normal).
