Development of recrystallization textures in ferritic stainless steels and their relationship to formability

Abstract

An investigation has been made into the development of recrystallization textures during the annealing of cold-worked ferritie stainless steels containing various alloying additions. The relationships between microstructure and composition, and yield strength, work hardening, and formability, have also been studied. The textures produced by various types of recrystallization nucleation site have been established, and the mechanisms of their formation have been discussed. Quantitative relationships have been determined for the effect of microstructure and composition on both the yield strength and the work-hardening rate for fully recrystallized structures containing no recovered substructures. Relationships have also been determined between the limiting drawing ratio. r-value, and a texture parameter which measures the intensity of the {111} textural component relative to the {100} component. It has been demonstrated that {111} textures are particularly beneficial to the deep-drawing characteristics.
