[Abstract]:The effects of synchronous and asynchronous cold rolling on the microstructure, texture evolution, mechanics and formability of SUS430 Ferric stainless steel were studied by means of X-ray diffraction and optical microscopic analysis. The results show that compared with synchronous cold rolling, the average grain size of asynchronous cold rolled sheet can be reduced due to the introduction of shear deformation in asynchronous rolling. In the process of synchronous cold rolling, the re-crystallization texture of secondary cold rolling is a complete gamma fiber texture, which leads to the final properties of Ferrified stainless steel are better than those of synchronous primary cold rolling. In the process of asynchronous cold rolling, the recrystallized texture of asynchronous primary cold rolling is a gamma fiber texture with strong point {111} 1 鈮，
