Characterization of Microstructure, Texture and Properties of a Continuously-Annealed Cold-Rolled High Strength Structural Steel

Abstract:

The mechanical properties, optical microstructure and textures of a continuously-annealed cold-rolled high strength structural steel were evaluated. The results show that the experimental steel has good balance of high strength and ductility, and the microstructure is composed of uniform, fine-grained ferrite and a little pearlite. The textures after recrystallization annealing are weak. The intensity of the strongest textures such as {114}<110> and {223}<110> are no more than 4. And the main {114}<110> and {223}<110> components are originated from the hot-rolling process and cold-rolling process, respectively, and preserved after annealing. The application of the experimental steel indicates that it can perfectly satisfy the stamping of some complicated structural parts in the automobile industry.
