mtex examples with data

I have been doing a bit of play using mtex to look at some EBSD data which I previous exported to .ctf format. mtex is an open source (GPL) software, which written for the commercial matlab software. The mtex package comes along with several examples and tutorials which can be read within matlab or over the http-internet-web.

Example scripts for using mtex are also available to download from the recently published paper “On Three-Dimensional Misorientation Spaces” by Krakow etal. published in Proceedings of the Royal Society A, 473, 2017.

Scripts and EBSD data for the case studies in the paper are available here:

Scripts for producing other figures in the paper (explaining orientation relations etc.) are available from the mtex website here (along with other examples):

Control of texture in materials using mtex /matlab at Sandvik

Dr Claes Olsson from Sandvik AB’s Materials Technology division explained at the Matlab expo 2016 how Sandvik has used the MTEX toolbox for analyzing and modeling crystallographic textures by means of pole figure and EBSD data. The software has been integrated into the work of the Materials Technology division allowing an auditable methodology for quality control, meeting standards to supply to their nuclear customers (e.g. in case of rolling zircalloy with controlled texture). Initial example of use was with pole figure data collected with a diffractometer, but they have also used the software to analyse EBSD data.

Mtex is a free toolbox released under the GNU GPL 2, which works inside the commercially available matlab environment.

Sequences game

I made a new game for by website at http://mathewpeet.org/, you can play [here].

In the game you have to say what is missing from the sequence presented to you.

I will be grateful for any suggestions for sequences I can add.

Using GSAS and EXPGUI in debian

EXPGUI is a graphical interface for the GSAS software, allowing structural refinement using the Reitveld technique.

EXPGUI/GSAS can be downloaded in binary form from http://www.ncnr.nist.gov/programs/crystallography/software/downloads.html

You need to install tcl/tk and also blt all of which can be found in debian package repositories. (Or whatever for your system!)

in debian:
apt-get tk8.4 blt

tcl/tk is the scripting language used to write EXPGUI.
failing to install blt will result in the error “Error — Unable to load the BLT package; cannot run liveplot”.
