摘要：

Self-diffusion of Mn-54 in Al72Pd20Mn8 icosahedral quasicrystals has been investigated over the temperature range from 723 to 1022 K. Concentration depth profiles of the radioisotope Mn-54 in the Al-Pd-Mn quasicrystals and crystals have been measured by an ion-beam sputter-sectioning technique. The temperature dependence of the self-diffusivity of Mn in Al72Pd20Mn8 icosahedral quasicrystals is expressed as D=(1.1(-0.5)(+1.0))x10(-10)exp(-134.+/-4.5k4mol(-1)/RT)m(2)s(-1). The self-diffusivity of Mn in Al72Pd20Mn8 icosahedral quasicrystals is about two orders of magnitude smaller than that in Al60Pd25Mn15 crystalline alloys. The self-diffusivity of Mn in the quasicrystals is abo three to four orders of magnitude lower than Mn diffusivity in crystalline Al.
