Notes:
In this study, the microstructure and the texture development in Al–Zn–Mg–Cu–Zr alloyswith/without 0.1%Sc has been investigated after extrusion, cold rolling, and aging treatment. Afteraging treatment, in Al alloy without Sc recrystallized equiaxed grains are obtained, while in Al alloywith Sc fine grains with an average size of 0.1~0.3 μm are obtained. After cold rolling, in case of thesample from the cross section (CS) to which Sc was added, texture with {112}〈111〉(Cu) + weak{123}〈634〉(S) component was developed while in case of the sample from longitudinal section (LS)to which Sc was added, texture with strong β-fiber + {110}〈001〉(Goss) components was developed.In case of CS and LS without Sc, texture of β-fiber was developed. After solid solution treatment andaging treatment, Al alloys (LS and CS) with Sc had rolling texture while Al alloys without Sc hadrandom texture. The role of these differently developed textures in the plastic behavior, such as thenormal anisotropy r-value (the plastic strain ratio) and planar anisotropy [removed info]r-values are discussed
