摘要：

The volume diffusion of(59)Fe in Al62Cu25.5Fe12.5 icosahedral quasicrystals is analyzed using classical diffusion techniques. Over the temperature range from 550 degrees C to 800 degrees C, the volume diffusion coefficients show a classical diffusion behavior and the temperature dependence can be expressed by the following relation: D-nu (m(2)s(-1)) = 4.53 . 10(-2) exp - 2.6 (eV)/kT In the absence of data on a crystalline phase with similar composition, diffusion coefficients are compared to those obtained for Fe in aluminium and in aluminides (FeAl and Al13Fe4): no strong peculiarity linked to the quasicrystalline structure appears.
