摘要	Plate-like Zr(61.5)Cu(21.5)Fe(5)Al(12) specimens were irradiated by 300 keV Ar(+) ions. X-ray diffraction results showed that the alloy specimens still maintained amorphous structures. High-resolution transmission electron microscopy and selected area diffraction results, however, showed that a nanocrystalline fcc phase was formed when irradiated to a fluence of 3 x 10(15) cm(-2). Differential scanning calorimetry analysis proved that the ion irradiations enlarged the supercooled liquid range of the amorphous alloy. Nanoindentation results showed further that the hardness and Young's modulus of the alloy increased with increasing ion irradiation doses. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd.
