Figure 1700 shows XRD patterns of Zr_70-xNb_xCu_13.5Ni_8.5Al₈ (x=0, 2, 4, 6, 7, 8, 10) alloys. The broad peaks in the patterns of the samples with Nb content <8 at.% indicate the samples are in amorphous phase. The patterns of the samples with 8 and 10 at.% Nb present an intense double peak and several weak peaks that is indexed in icosahedral phase (I-phase) [2–4].
