Abstract: Based on the similarity of some of the quasi-crystalline alloy′s structures and atomic energy band factors, an empirical composition addition principle for multi-component quasi-crystal constitutions was proposed, which has been tested positively in many quasi-crystal alloy systems such as Al-Cr-Mn, Al-Cu-Fe- Cr-Mn, Al-Cu-Fe-Pd-Mn, Al-Cu-Fe-Mg. These newly constituted quasi-crystals possess various formation characteristics; they can be prepared through rapid solidfication process(RS), ingot metallurgy process(IM), annealing or high pressure, high temperature treatment of RS powders. The function of this principle was discussed.
