Texture

Texture, the distribution of crystallographic orientations in a polycrystalline sample, can be measured using X-ray diffractometers with specific goniometers and hardware configurations. Texture is observed in the majority of engineered materials and can influence material properties such as mechanical strength and formability. Through tilting and rotating the sample, the intensity of a certain (hkl) reflection can be measured over the entire orientation sphere and a pole figure recorded. Sets of pole figures can then be used to calculate the orientation distribution function (ODF). Knowledge of the evolution of preferred orientations can provide valuable quality control information in order to optimise manufacturing processes.

We carry out texture analysis and train researchers to perform texture analysis on metals and alloys and additively manufactured materials.
