Abstract
The presence in cold-rolled electrolytic copper sheet of a texture of the type {134}, [4¯85] has been established by x-ray methods and by analysis of the elastic anisotropy. The modulus diagrams of the sheet are described by a Fourier series of the form: E = r0 − r2 cos2ϕ + r4 · cos 4ϕ.
After annealing at temperatures up to 160 °, the free term in the expansion slowly increases, while the amplitudes of the second and fourth harmonics remain unchanged. Above 160 ° the second harmonic gradually disappears in the course of recrystallization, and the amplitude of the fourth harmonic increases at the same time. The modulus diagram is described by the series E = r0 + r4 cos 4ϕ.
Fourier analysis reveals the steady development of the orientation (100) [001], even in the initial stages of recrystallization, although x-rays show no traces of the new structure up to 250 °.
