Abstract

Zr65Al7.5Cu27.5(Z-3), Zr65Al10Cu15Ni10(Z-4)and Zr55Al15Cu15Ni10Ti5(Z-5)glassy wires with a large supercooled liquid region were produced by a newly designed method, i. e., melt extraction using an arc furnace. The wire has a circular cross section and a smooth peripheral surface, but small flaws are observed on the surface. The Tg and Tx of the Z-4 and Z-5 glassy wires are nearly the same as those of the melt-spun glassy ribbons. The Z-4 glassy wire has a large super coold liquid region of 95 K. The coefficient of thermal expansion of the Z-4 glassy wire is 9.2 × 10-6K-1 and the temperature of electrical resistance of the Z-5 glassy wire is-9.0×10-5 K-1, respectively. Tensile fracture strength and elongation are 1170 MPa and 1.9 %, respectively, for the Z-3 glassy wire and 1590 MPa and 2.2 %, respectively, for the Z-4 glassy wire. The fracture surface consists mainly of a vein pattern which is the same as that for amorphous alloys.
