Trans. Nonferrous Met. Soc. China 22(2012) 1123-1126 Effect of minor-addition of Fe on structural and mechanical properties of CuZrAl bulk metallic glass XU Hong-wei1,2, DU Yu-lei1,2, DENG Yu3 1... Received 19 September 2011; accepted 12 January 2012 Abstract: The CuZrAl bulk metallic glass with minor-addition of Fe was prepared by rapid quenching method. The structures were examined by X-ray......
, Vickers hardness, electrical conductivity, tensile properties test, intergranular corrosion and transmission electron microscopy. The hardness of the alloys aged at 180 ℃ increases to a peak value... in T6 and T4 increase, and the resistance to intergranular corrosion decreases, but the alloy without Cu does not present intergranular corrosion sensitivity. The kind of the precipitates in the T6......
