Effect of molybdenum on texture evolution in 0·015C–1·5Mn steels

Abstract

The effect of molybdenum on the texture evolution of cold rolled and annealed steel sheets was examined in a series of 0·015C–1·5Mn–Mo steels. Orientation distribution function data were calculated from the (110), (200) and (211) pole figures determined on the rolled plane of cold rolled and annealed steel sheets. Increasing the Mo content markedly strengthened the intensities of γ fibre textures, but the {001}<110> and {110}<110> textures were not affected by the Mo content, which resulted in an increase in r _m value. The desirable texture evolution for the deep drawability in 0·5%Mo steel may be mainly caused by the grain refining effect of Mo in the hot rolled steel sheet.
