Can quasicrystals survive in planetary collisions?

Abstract We investigated the compressional behavior of i-AlCuFe quasicrystal using diamond anvil cell under quasi-hydrostatic conditions by in situ angle-dispersive X-ray powder diffraction measurements (in both compression and decompression) up to 76 GPa at ambient temperature neon as pressure medium. These data were compared with those collected 104 KCl medium available literature. In general, sets indicate that individual d -spacing shows a continuous decrease no drastic changes associated structural phase transformations or amorphization. The / 0 , where is pressure, showed general isotropic behavior. zero-pressure bulk modulus its derivative calculated fitting volume Murnaghan- Birch-Murnaghan equation state models. Results from this study extend our knowledge on stability icosahedrite very high reinforce evidence natural quasicrystals formed during shock event asteroidal collisions survived for eons history Solar System.
