“…Our recent investigations on approximant phases and CMAs also showed that these relatively close-packed structures show no transitions at higher pressures, as e.g. the W-Al--Co--Ni phase (Krauss, Gu, Katrych, Deloudi and Steurer, 2007), Rh 3 Bi 14 (Gu, Krauss, Grin and Steurer, 2007) or Mg 2 Co 3 Sn 10þx (Krauss and Gu, 2008). It turned out, as could be expected, that the bulk modulus is more related to the constituting elements than to the crystal structure.…”

Abstract. The stability of C2-Al 64 Pd 30.4 Fe 5.6 , an approximant phase to the icosahdral Al--Fe--Pd quasicrystal, has been investigated by high-pressure X-ray diffraction using a diamond-anvil cell and synchrotron radiation up to 24.30(1) GPa. The material is structurally stable within the framework of the experiment. The unit cell volume as a function of pressure follows a second-order Birch-Murnaghan equation of state with K 0 ¼ 169.5(2.5) GPa. This value is comparable to that of other quasicrystals and approximant phases containing Al and heavy transition metals.

“…The Co1 atoms have coordination number (CN) 8 in a squareantiprismatic fashion, and Co2 has CN 6 in the form of trigonal prisms. A high-pressure study in a diamond anvil cell showed stability of the Mg 2 Co 3 Sn 10+x structure up to 9 GPa [12].…”
