摘　　要：Effects of proton irradiation on structure re-laxation of Zr41.5Ti14.9CU12.6Ni10.5Be20.4 bulk metallic glass areinvestigated by means of X-ray diffraction, differential scan-ning calorimetric and electronic resistance measurements.The results show that, at 203 K, the structure of Zr41.5Ti14.9CU12.6Ni10.5Be20.4 bulk metal glass is relaxed obvi-ously by proton irradiation with the energy and the dosebeing of 160 keV and 1.65x10^16 ions/cm^2, respectively. How-ever, Zr41.5Ti14.9CU12.6Ni10.5Be20.4 bulk metallic glass becomesmore steady amorphous state under two conditions, one isthat the energy and the dose are 160 keV and 1.1×10^15 ions/cm^2, respectively. Another is that the energy and thedose are 120 keV and 6.5×10^15 ions/cm^2, respectively.Effects of proton irradiation on structure re-laxation of Zr_(41.5)Ti_(14.9)Cu_(12.6)Ni_(10.5)Be_(20.4) bulk metallic glass areinvestigated by means of X-ray diffraction, differential scan-ning calorimetric and electronic resistance measurements.The results show that, at 203 K, the structure ofZr_(41.5)Ti_(14.9)Cu_(12.6)Ni_(10.5)Be_(20.4) bulk metal glass is relaxed obvi-ously by proton irradiation with the energy and the dosebeing of 160 keV and 1.65×10^(16) ions/cm^2, respectively.
