Abstract

Heat capacities and thermal expansion coefficients for a decagonal Al₇₂Co₁₆Ni₁₂ single-grain quasicrystal were determined in the temperature range 5-300 K. The linear thermal expansion coefficient obtained at 300 K parallel to the ten-fold axis is approximately 10% larger than that perpendicular to the axis. This anisotropy becomes more prominent at low temperatures, resulting in quite anisotropic Grüneisen parameters. The measurements were also made for comparison for an icosahedral (isotropic) Al_71.7Pd_19.4Re_8.9 single-grain quasicrystal.
