摘要

The effect of cold rolling on the recrystallization texture and ridging of AISI 430 type ferritic stainless steel is investigated. For comparison, the steel was cold-rolled under different reductions, two-stage rolled, and cross-rolled, respectively, and the recrystallization texture was determined by EBSD and microstructure was characterized by SEM, and the uniaxial deformation was conducted on MTS electronic universal material testing machine. The results show that in the one-stage cold rolling and annealing process, gamma-fiber texture component increases with the rolling reduction, and the maximum orientation density of which appears at {334} orientation with a slight deviation from {111}. The intensity of {100} texture decreases and the other main texture components remain unchangeable. After two-stage cold rolling, the recrystallization texture returns to the gamma-fiber texture that is of the feature of the ordinary bcc metals, while cross-rolling results in a recrystallization texture of mainly {100} and {111} components. It is indicated that intermediate annealing obviously improves the deviation of orientation from gamma-fiber texture, which is beneficial for the steel obtaining the typical texture of bcc metals. By one-stage cold rolling and annealing process, AISI 430 type ferritic stainless steel possesses a microstructure with the texture components of {100}, {211}, {111} and {111}, with clusters of {111}, {hkl} and {hkl} grains, which deteriorates the ridging resistance, while in the two-stage rolling and annealing process, the microstructure of dispersed oriented grains shows a much better surface ridging resistance.
