The present paper introduces new texture measurement methods developed
for mobile/fixed centreless X-ray diffractometers. Using these methods, pole
figures can be obtained with all the benefits of centreless diffractometers: no
need for sample cutting, flexibility in case of large components with complex
shapes, short measuring time and portability. The paper describes the
measurement methods, includes the validations with conventional pole figure
measurements and provides instances of applications of the new technique. The
possibilities offered by the techniques are shown through practical
implementations of the methods from the field of metal forming, mineralogy,
and archaeometry using a certain operation mode of centreless X-ray
diffractometer. The execution of the measurements and the required minor
hardware modifications are also presented.
