In this contribution, the ehavior of three types of steel after rolling was investigated. Ferritic and aubstenitic steels or phases have different mechanical and thermal properties. Due to their mutual influence during plastic deformation, it is possible to suppose the differences between preferred orientations of austenite and ferrite phases in duplex steel and single-phase austenitic and ferritic steels. For this reason, the preferred orientations of austenite and ferrite phases of rolled duplex steel were compared with rolled single-phase austenitic and ferritic steel. The 0-50% reductions of rolled steel plates were selected. Mainly, the strength and type of preferred orientation were compared in the relation to reduction and material. For this purpose, the rolled surfaces were measured by X-ray diffraction. The significant differences between intensities and types of texture components were investigated. For austenite-ferrite interaction during plastic deformation and phase transformation, samples were analysed by electron back-scattered diffraction. The Kurdjumov-Sachs orientation relationship was investigated.
