Special Issue Information

Dear Colleagues,

Crystallographic texture is a rich and frequently investigated subject in the field of materials science due to its decisive impact on the anisotropy of properties. In this Special Issue, we gather papers related to crystallographic texture and anisotropy of polycrystalline metallic materials. Original research papers and review papers are also welcome. Contributions in all aspects of the main focus area are of interest, such as novel approaches of characterization, modelling, experimental studies, applications and/or the combination of these. This Special Issue can be expected to be of interest to a wide range of researchers within materials science.

The volume fraction of austenite (γ), ε martensite and α′ martensite is of key importance in the research of TWIP/TRIP steels. When mechanical loading is involved, the crystallographic texture also develops, which complicates X-ray diffraction-based phase ratio determination. The problem is more pronounced when only a couple, or only one Bragg-reflection can be measured. A solution for such cases is to determine the ratio of the phases based on the pole distribution function of a selected Bragg-reflection of the present phases. In this manuscript, this method is reconsidered for and applied to non-transmittable bulk specimens for the first time in the reflection mode of XRD pole figure measurements. First, the method was applied to a series of γ–α′ powder mixtures. The results were compared to those obtained by the Rietveld method. Afterwards, the technique was applied to strongly textured, bulk TWIP/TRIP steel specimens which were tensile tested at different temperatures. It was shown that the results of the presented method were close to those of the Rietveld technique in the case of powder mixtures. The results of the tensile-tested steels revealed that the α′ content increases with decreasing test temperatures, and the variation of the α′ ratio correlates very well with the ultimate tensile strength versus the temperature, confirming the contribution of the α′ content to the strength of TWIP/TRIP steels.
