Specific heat of quasi-crystals

Molar heat capacity from 310 to 873 K has been determined for Al94Fe2V4 ribbon. The classical integral step-by-step method and the dynamic mode differential scanning calorimetry method dates were mutually related. Specific heats of all Al-rich multicomponent nanostrustured systems, i.e containing amorphous, quasicrystalline or crystalline grains of nanometer dimensions, are anomalously low reflecting the presence of another Al-rich phase – the interphase.
