快速凝固Al-Mn合金（成分范围18-22 at.%）中相形成的研究Mn）的结果表明，一个二十面体相被另一个非晶体相，一个十面体相所取代。十次对称相是准晶的另一个例子：它具有非晶体学点群（10 m或10 mmm），以及长程取向有序和一维平移对称。从对称性和凝固条件的观点来看，十面体相是二十面体相和晶体之间的中间相。
Studies of phase formation in rapidly solidified Al-Mn alloys (composition range 18-22 at.% Mn) show that an icosahedral phase is replaced by another noncrystallographic phase, a decagonal phase. The decagonal phase is another example of quasicrystal: It has a noncrystallographic point group (10 m or 10 mmm) together with long-range orientational order and one-dimensional translational symmetry. The decagonal phase is an intermediate phase between an icosahedral phase and a crystal both from the symmetry and from the solidification condition points of view.
