Microstructure and texture of ferritic stainless steel for automotive exhaust system

摘要：

The microstructure,texture and grain boundaries character distribution of Nb + Ti stabilized ferritic stainless steel for automotive exhaust system were analyzed using scanning electron microscopy,transmission electron microscopy and X-ray diffraction.The addition of alloying elements such as Ti and Nb to ferritic stainless steel causes the formation of TiN and NbC.The texture of cold rolled samples were dominated by the α-fiber,while,the texture of annealed samples are very strong γ-fiber.The changes in texture are closely related to the grain boundaries type.
