中文摘要	Irradiation effect of the Al76Si4Mn20 icosahedral quasicrystal (IQC) caused by 120 keV Ar ions and 1 MeV electrons has been studied by using transmission electron microscopy (TEM). The effect is dose and temperature dependent. At lower temperatures (less-than-or-equal-to345 K), Ar ions induces the Al-Si-Mn IQC fully amorphized. At medium temperature (352approximately400 K), only weak disordering and amorphization effects have been observed. At higher temperature (520approximately670 K) no measurable effect has been observed by TEM. The temperature ranges are shifted to much lower temperatures for 1 MeV electron irradiation. The Ar ion and electron dual irradiation possesses the same effect as Ar ion irradiation. Heating the amorphized specimen to 600approximately640 K induces it to transform to micro-quasicrystals and further heating to higher temperature (greater-than-or-equal-to660 K) induces crystallization.
