Abstract
Orientation relationships between deformation and annealing textures of chromium-nickel austenitic stainless steel have been analysed in the present paper. Two austenitic steels of different chemical compositions and phase stability were investigated after deformation and annealing i.e. the X7CrNi24-11 and XIOCrNi18-7. Since both steels exhibited stable and metastable austenite structure a different deformation and annealing textures were obtained in each of them as a consequence. The texture of austenite after deformation of both steels showed the brass type texture (110) < 112 >. The appearances of the {111} < uvw > components in both textures resulted from mechanical twinning. The texture of the alpha'-martensite formed in the metastable steel during deformation became stronger with increasing deformation degree. The orientation relationships between the major austenite and martensite textures components were best described by Kurdjumov-Sachs orientation relationship. The appearance of new orientations in the austenite texture was observed after annealing of the stable steel, apart from the weakening of main texture component, In order to determine crystallographic relations between deformation and annealing textures, the transformation of ideal orientations as well as experimental orientation distribution functions (ODFs) was carried out without variant selection. It was found that twin relation, (that is the 60 degrees < 111 > rotation) described these relationships in an appropriate way. However, the process of oriented growth might have also affected also the annealing textures of austenite to some extent. Crystallographic relations between the orientations from the annealing texture of austenite and the deformation texture of martensite in the metastable steel followed best the Kurdjumov-Sachs relationship. Additionally, some texture relations of the deformed and annealed austenite were described by a twin relationship. The orientations describing texture of annealed austenite resulted from both, the inverse transformation (alpha' -> gamma) and the recrystallisation of deformed austenite.
