Notes:
After extrusion, cold rolling and T-6 treatment, microstructure, texture development, and deep drawability of Al-5.09%Zn-1.83%Mg-0.32%Cu-0.25%Mn-alloy with 0.1% Sc are studied. After T-6 treatment, recrystallized equiaxed grains with an average grain size of 1~2㎛ are obtained. During extrusion the very strong 〈111〉-fiber + medium sharp 〈100〉-fiber + weak 〈210〉-fiber texture is developed, which influences the formation of rolling texture. The texture, after 80% cold rolling, can be described by the strong {112}〈111〉(Cu) + {123}〈634〉(S) component in the cross section of the extruded rod, the strong b-fiber + weak {110}〈001〉(Goss) components in the longitudinal section, and the strong {110}〈112〉(Bs) + weak {001}〈100〉(Cube) components in the transverse section. The types of rolling texture are not changed after the T-6 treatment, but the maximum density of ODF is higher. The calculated mean r-values, rm, and the planar anisotropy, Dr, are relatively high, which are dependent on the texture
