Effect of B on Textures of Fe-36%Ni Alloy

Effect of B addition (B≤0.012%) on the cold rolling and recrystallization textures of Fe-36%Ni alloy has been studied.The {001} preferred orientation, which is increased with increasing B contents, developes in the surface layer. The surface rolling texture penetrates from the surface to a depth of less than about 20μm. The pure-metal type rolling texture of {4 4 11} which is found in the inner layer, irrespectively of B contents. The surface recrystallization texture of B containing alloys is almost random. The inner recrystallization texture showes a gradual change with increasing B contents from the {100} orientation to the {4 4 11} orientation of rolling texture which is retained after completion of recrystallization.
