Stereographic projection representation of {100}, {111}, {110} pole figures of the Cu-based materials: (a) Cu R, (b) Cu R + A, (c) Cu15Zn, (d) Cu18Ni20Zn. The scale at the bottom right for each pole figure reports the coldest colour to the lowest pole density value and the warmest colour to the highest pole density value. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
