Transmission electron microscope bright field images of (a) microstructure, (b) Cu-Zr IM phase, (c) Cu phase, (d) nanocrystalline phase of Cu86Zr11Al3, and of (e) microstructure, (f) Cu-Zr IM phase and (g) Cu phase of Cu85Zr10Ti5. Each inset is the selected area diffraction pattern of the corresponding image. Small black contrast in (c,f) would be produced by FIB milling during TEM sample preparation. The fine line structures in (b,g) are produced by the alternating layered superlattice structure of Cu5Zr.
