采用同步辐射原位高压X射线粉末衍射研究了二元CdCa准晶的结构稳定性。结果表明，在47 GPa压力下，样品的二十面体准晶结构是本征稳定的。二十面体CdCa准晶的零压体积弹性模量为68.1± 2.0GPa，零压体积弹性模量的压力导数为4.3±0.2。 不同布拉格峰的压缩行为是各向同性的，表明在稳定的二元二十面体CdCa准晶中没有压力诱导的各向异性弹性。
The structural stability of a binary CdCa quasicrystal with a primitive icosahedral structure has been investigated by in situ high-pressure x-ray powder diffraction at an ambient temperature using synchrotron radiation. It is demonstrated that the icosahedral quasicrystalline structure of the sample is intrinsically stable up to 47 GPa. The bulk modulus at zero pressure and its pressure derivative of the icosahedral CdCa quasicrystal is 68.1±2.0 GPa and 4.3±0.2, respectively. The compression behavior of different Bragg peaks is isotropic, indicating no pressure-induced anisotropic elasticity in the stable binary icosahedral CdCa quasicrystals.
