Abstract

Amorphous Cu_50-xZr₄₅Al₅Nb_x (x = 0, 1, 3 and 5 at.%) samples with critical diameters of 1.54-2.05 mm were formed by copper-mold suction casting. The effects of Nb on the glass formation ability were evaluated with differential scanning calorimetry and the corrosion resistances of the alloys with the addition of Nb were evaluated in 1 N HCl, 3% NaCl and 0.5 N H₂SO₄ solutions, respectively, by weight loss and polarization curve measurements. The samples surfaces were examined after the corrosion test with SEM. It was found that the addition of Nb causes a decrease of ΔT_x of Cu_50-xZr₄₅Al₅Nb_x alloy from 54 K to 45 K. On the other hand, the corrosion resistances in various solutions were improved with the addition of Nb. © 2007 Elsevier B.V. All rights reserved.
