Grain Boundary Texture
Recently the distribution of grain boundary planes in metals and other materials has begun to be studied in addition to the misorientation distribution. It has been found that a ‘grain boundary texture’, i.e. a non-random distribution of grain boundary planes, often exists. The present paper will show examples of grain boundary texture taken from austenitic stainless steel and rocksalt. The characteristics of the grain boundary texture will be described in terms of low-index boundary planes and tilt/twist descriptors. Reasons for the formation of the particular grain boundary texture and possibilities for exploitation via grain boundary engineering will be discussed.
