The evolution of recrystallization textures in body centred cubic metals

A model of the evolution of recrystallization textures for b.c.c. metals was suggested based on the ODF and EBSD analysis of the texture change during annealing of cold rolled steel. The model is composed of two principles: first, the maximum principal stress direction in the deformed grain becomes the minimum Young's modulus direction in the recrystallized grain; second, a {110} plane, parallel to the maximum principal stress direction (hence, minimum Young's modulus direction), is taken for variant selection. The current model is successfully applied to describe the evolution of recrystallization textures in various b.c.c. transition metals such as tantalum, molybdenum and tungsten.
