利用电子衍射在正常凝固Al65Cu20Co15合金中观察到不属于Fibonacci序列的新的空位有序超结构相τ23,τ27和τ35。衍射强度计算表明其堆垛方式分别为332323232,3323323323和3323323323323。By using electron diffraction method, three new vacancy ordered phases, τ23,τ27 and τ35, have been found in the conventionally solidified Al65Cu20Co15 alloy. They do not belong to the known Fibonacci series The computed kinematical intensities shown that the stacking sequences of τ23,τ27 and τ35 are respectively 332323232, 3323323323 and 3323323323323.
