On the cold rolling textures in some fcc Ni-W alloys

The development of thin, mechanically stronger and highly cube textured substrates is of great technological importance for increasing the engineering current density of coated superconductors. Due to the development of a strong recrystallisation cube texture and improved strength, Ni-W alloys are good candidate substrate materials for the development of coated superconductors. It is well known that the recrystallisation cube texture is strongly related to the rolling texture, which in turn is related to the alloying content, temperature of deformation, etc. In the present paper, we report the copper-type to brass-type texture transition in the rolling texture of cold rolled fcc Ni1-xWx alloys at W contents >5 at.%. The possible reasons for the above texture transition and the consequences on recrystallisation texture are discussed. (C) 2004 Elsevier B.V. All rights reserved.
