Extract

The thermal diffusivity of several quasicrystalline and related crystalline alloys was measured both at room temperature and as a function of temperature. It is found remarkably small as compared to conventional metallic alloys. It changes slightly when reversible phase transition takes place and is definitely smaller in the quasicrystalline state than in the corresponding “approximant” state.
