Abstract
The amorphous Zr64.5Cu35.5 alloy ribbon was prepared and annealed in a high vacuum furnace at 645 K (372 °C) for different times. It was found that the main crystallization phases in the alloy ribbon are CuZr2 and CuZr3. The grains of CuZr2 show special orientation relationships. The grains in opposite dendrites show the same orientation, and adjacent dendrites behave as a twinlike orientation with a (103) twin plane. The CuZr3 with a superstructure is discovered in annealed ZrCu metallic glasses.
