In an alloy with nominal composition of Al67Cr15Cu18 annealed at 900 degreesC and below, microdomains of decagonal approximants have been identified by means of transmission electron microscopy. High-resolution images show that the microdomains, whose electron diffraction patterns display almost perfect tenfold rotation symmetry, are composed of three crystalline approximants intergrown with each other. The crystallographic relationships between these phases are given; and phase transformation between decagonal quasicrystal and its approximants is discussed.
