DTA curves of a representative series of amorphous alloys, formulated as (at. %), where , as marked in the figure. The heating rate is 20 °C∕min.
XRD patterns of the series of as-made ingots of . The ingot weight is 2 g unless marked. The dotted lines represent the three dominant diffraction peaks of the icosahedral quasicrystalline phase, where A, B, and C are (100 000), (110 000), and (101 000), respectively.
Compression true stress-strain curve for the 3 mm amorphous rod. The inset image shows the processability of this amorphous alloy.
Bright-field TEM image (at bottom) and corresponding fine probe electron diffraction patterns illustrating the two-fold, three-fold, and five-fold (at top, from left to right) symmetries of the quasicrystalline phase. Initial sample was a 2 g as-made ingot of .
