Preferred orientation has been examined in extruded, drawn, and swaged nickel, nickel-20% chromium, and nickel-20% chromium-l0% tungsten, with and without a dispersion of 2 vol.-% of thoria particles. Duplex 〈100〉 + 〈111〉 fibre textures were observed in most cases. The 〈100〉 component was stabilized by the presence of particles and also by the application of intermediate anneals during deformation. These results and the stability of the deformed state in thoriated nickel are attributed largely to the action of the particles in generating homogeneous deformation.
