抄録

The planar anisotropy of the r-value of duplex stainless steel sheets showed reverse V-type. To ascertain the possibility of control, the anisotropies and textures of cold-rolled and annealed sheets with different amounts of nitrogen, based on 21.2%Cr-1.5%Ni-5.0%Mn-0.02%C steel, and for different annealing temperatures after hot rolling were investigated. With a decrease in the amount of nitrogen and an increase in the annealing temperature before cold rolling, the anisotropy changed to V-type from reverse V-type. In addition, the singular texture with weak α_bcc-fiber and strong Goss orientation in the α phase of the low-nitrogen added sheet was observed.
