Title: Grain boundary distributions, texture and orientation correlations in austenitic stainless steels

Abstract

Among various distribution functions describing microstructure of polycrystals, two relate to the crystallite orientations, namely, crystallographic texture and misorientation distribution. Complications arise due to the orientation correlations which may exist between various crystallites of the polycrystalline aggregate. These two factors, viz. texture and orientation correlations, determine the grain boundary distribution in a sample. Contributions of these factors to the misorientation distribution as a whole and to the fractions of specific grain boundary types are yet to be fully understood. Studies have shown that in some materials grain boundary distribution is primarily determined by texture, whereas the orientation correlations may play a dominant role in the others. Another point that requires clarification is as follows: Crystallographic texture may be described either by macrotexture determined by the X-ray analysis, orientation distribution function (ODF) being its most general representation, or by microtexture represented as a set of individual crystallite orientations in some area of the material. It is not a priori clear whether misorientation distributions derived from microtexture and macrotexture would be the same. These are the questions addressed in the present paper. This work is an extension of the authors` previous publications.
