The value of Δr is positive up to 30% reduction, but it changes to negative for the reduction higher than 40%. It means that the sheets are anisotropic, but become rather isotropic for large rolling reduction. The change in n-value is shown in Fig. 3. The n-value decreases abruptly up to 20% reduction and remains at low level for higher reduction.
