Texture evolution during cold rolling and recrystallization of L12-type ordered Ni3(Si,Ti) alloy

Texture evolution during cold rolling and recrystallization of L12-type ordered Ni3(Si,Ti) (Ni79Si11Ti10, denoted by at.%) alloy was investigated. The starting material with no preferential orientation was cold rolled up to 80% reduction, and then fully recrystallized by annealing at 1173 K for 1 h. After cold rolling, a copper type texture composed of the α- and β-fiber textures with the strongest component of {011}〈211〉 orientation was developed. The recrystallization textures depended on rolling reduction. For the 30% reduction, no textural change was observed, while above 50% reduction the recrystallization textures were quite weak, but {011}〈100〉 and {001}〈110〉 orientations apparently existed. Based on these results, formation mechanism for cold rolling and recrystallization textures of the Ni3(Si,Ti) alloy was discussed and compared with those of other L12-type ordered alloys.
