摘要
A processing sequence is described for producing specific controlled elongated oriented crystal structures in nickel base superalloys. The method is performed in the solid state. Superalloy material is provided in a dense workable form. The material is cold straight rolled and cold cross rolled with intermediate anneals. This sequence produces a particular texture or preferred orientation in the rolled article. This textured article is then directionally recrystallized to produce the desired final microstructure comprised of aligned elongated grains of a particular controllable orientation.
