Rocks

Göttingen, Germany
WORKSHOP 4:
Helmut Klein and Klaus Ullemeyer
(Göttingen):
Texture determination with X-rays and neutrons - advanced methods
Volume texture studies are usually carried out by means of X-ray and
neutron polycrystal diffraction providing pole density distribution
functions (pole figures). First texture analyses have been performed in
metals which are characterized by relatively simple crystal structures with
high crystal symmetries. Recently, other materials such as ceramics,
polymers, semiconductors, intermetallics or composites and geological
materials have come into the field of interest. These materials have much
more complex crystal structures in comparison with the basic metals and
therefore complicated, line-rich diffraction patterns. Quantitative texture
studies of such materials require more sophisticated experimental
techniques and data evaluation methods.
The aim of the workshop is to monitor the rapid progress in the field of
pole figure measurements.
Specific topics are:
Aims of volume texture measurements
Novel methods of X-ray texture analysis
Time-of-flight neutron diffraction
Synchrotron radiation
New detectors (linear, area and energy dispersive detectors)
Glass capillary optics
Oral contributions, posters and software demonstrations concerning methods
of volume texture measurement and treatment of texture data are invited.
