Abstract

A new cell has been developed for measuring the thermal diffusivity of small samples [about (5x2x0.5) mm3], using the laser flash method. The thermal diffusivities of small samples of titanium, SUS304 and Pyrex 7740 glass measured with this cell agree well with those obtained from samples of 10 mm in diameter and 0.4 mm in thickness. Then, the thermal diffusivity between 300 K and 950 K of quasicrystalline Al72Pd20Mn8 with a single domain size of 5 mm, and that of crystalline Al60Pd25Mn15 were measured. The thermal diffusivity of quasicrystalline Al72Pd20Mn8 was found to be 4 to 7 times smaller than that of crystalline Al60Pd25Mn15.
