The roll deformation texture for high purity nickel strip can be described approximately as a spread around the four equivalent ideal orientations of the type (123) STA121!. The annealing texture is essentially the cube texture (100) STA001!. In nickel and nickel contninlng small amounts of chromium and cobalt, small reductions, about 40%, produce a small degree of texture around the (123) STA121! orientation. The slight amount of cube texture produced on annealing does not significantly reduce the Young's moduli of the alloys. For a given amount of reduction, a more pronounced roll texture, around the (123) STA121! orientation, is produced in dispersion hardened nickel than in high purity nickel. The annealing texture of dispersion hardened nickel is cube, with pronounced twin components. Most of the grnins appear to be twinned, even after annealing for 1 hour at 1200 deg C. The roll texture for Nimonic 75, 80A, and 90 strip, reduced by 40%, can be described approximately as a spread around the ideal (110) STA112! and (112) STA111! orientations. Nimonic 80 A and 90 recrystallize to random grain orientation. For Nimonic 75 the recrystallization texture is similar to the roll texture, but appears to be sharper and to have a stronger (112) STA111! component. The high temperature extrusion texture of nickel is random, but that of dispersion hardened nickel is predominamtly cubic. The high temperature extrusion texture of the Nimonic alloys tends to be cubic, but the proportion of randomly oriented grains increases with the total titanium + aluminum content. The drawing texture of nickel wire consists mainly of (111) fibre texture; the annealing texture of drawn nickel wire, drawn 83%, is random for annealing temperatures below 500 deg C. The drawing texture of dispersion hardened nickel wire may be a mixture of (111) and (100) fibre textures; during annealing the proportion of (100) fibre texture increases slightly. (auth)
