Abstract

Three dimensional texture analysis by means of orientation distribution functions (ODF) was used to examine the texture development during rolling at 473 K in an austenitic stainless steel. With the help of ODFs results, the different stages of texture development could be assigned to the existing theories of heterogeneous deformation mechanisms of low SFE face-centred cubic metals. The texture at very low degree of rolling consists of two limited orientation tubes with their fibre axes 110//ND and 11060ND and agrees with the predictions made by Taylor model. With further deformation, twinning causes the reduction of {112}111 component and leads to the formation of twin {552}115. Abnormal slip on slip planes parallel to the twin boundaries rotates the twins into the {332}113 and {111}110 positions. The shear bands formation in the rotated twin-matrix lamellae changes their orientations near to {011}100 and {011}112 positions. Finally, normal slip again continues and sharpens the brass-type rolling texture.
