EBSD or X-Ray for Texture measurements ?
EBSD or X-Ray for Texture measurements ?
(OP)
I am doing some metallurgical research at university and I could not figure out, by the articles I’ve read, which are the most important differences between texture measurements using EBSD and X-Ray.
ex.: Ultra high purity materials (Fe-Nb; Fe-Cr; Fe-Nb-C and combinations of these elements. Hot deformed.
When a particular technique should or not be used? Advantages of each? EBSD textures are really reliable?
EBSD is good for making statistics? X-Ray is faster?
If any of you could contribute with your knowledge I would be grateful.
Best wishes,
Maleck.

You might wnat to talk to your professors about this one, or other studnets or the technical staff in the charecterization area.

I don't want ot scare you maleck, but most of us have done this only in school, using X-ray dif, and analized it by HAND.

First it depends on the objective of your research. But normaly we determine the material texture first by X-Ray to get a global texture before using EBSD to get a local texture.
Globally, X-Ray diffraction is for global texture determination and EBSD is to have a microstructure-texture data. It means that with EBSD, you can have at the same time the microstructure and also the crystal orientation at each point of your microstructure. So you can analyse the grain boundary character, the misorientation between grain, which phase in grain boundary (if it big enough).
Avantage of X-Ray is that it gives more statistically representative texture determination compared to EBSD. With Y-Ray goniometer, the beam interact normally with bigger volume than with EBSD, so there are more grains taken into account for texture determination.
While with EBSD, the interaction volume is much smaller. Microstructure-texture technique provides concurrently the spatial location and the orientation of individual grains in a sample.

Viva texture!
