Texture evolution of 409 ferritic stainless steel tubes through severe plastic deformation and subsequent annealing

Since most of properties of Ferritic Stainless Steels (FSS) is dependent on their crystallographic texture, investigation on the evolution of texture of these alloys through metallurgical processes seems important. However, although different studies are focused on this topic, they have usually considered evolution of texture through conventional forming processes such as rolling while evolution of texture of these steels through severe plastic deformation is less studied. Therefore, the aim of this work is to investigate the evolution of texture of FSS 409 through imposition of a recently developed severe plastic deformation process called Tube Channel Pressing (TCP) accompanied by a subsequent annealing. Results show that processing by TCP and a subsequent annealing weakens the initial texture of tube derived from the rolled sheet. In addition, Lankford value in both of the circumferential and longitudinal directions of tube increases after the applied treatment due to arising of new texture component as well as removal of a few of initial texture components.
