It is generally believed that long range periodic order is instrumental in the formation of a photonic band gap. Using a spectral method that scales linear... Y Chan,C Chan,Z Liu - 《Physical Review Letters》 被引量: 498发表: 1998年 Quasicrystals in as-cast Mg-Zn-RE alloys Since the ...
Here we demonstrate the formation of extended binary quasicrystalline precipitates with Penrose-like random-tiling structures, beginning with chemical ordering within the pentagonal structure at cores of prismatic dislocations in Mg–Zn alloys. Atomic resolution observations indicate that icosahedral chains ...
Recognizing quasicrystals that are embedded in Al-based cast alloys is a challenging task. For this reason, we synthesized a series of multi-component, AlMn-based alloys that contain many icosahedral quasicrystals in addition to crystalline phases. We then conducted a thorough investigation in order ...
Thus, the addition of nickel or iron favors quasicrystal formation in the suction cast Al-6wt.% Mn alloys. Based on a 4:1 matching ratio of aluminum atoms to heavier atoms, the approximate electron to atom ratio is 1.85 in two decagonal phases of Al56Mn11Ni2 and Al40Mn7Fe2. Various...

We describe some theoretical and experimental tools developed to understand simple alloys from the point of view of statistical physics. Generalizations to quasicrystals are discussed, particular attention being paid to the interpretation of diffuse scattering....
Example 3: Elasto-Dynamics of Plane Elasticity of Dodecagonal Quasicrystals Let us take the z-axis as periodic direction in point group 12 mm dodecagonal quasicrystals. Suppose that the field variables not depends on the coordinate z, then the elasticity problem of dodecagonal quasicrystals can ...
