摘要：

Wires of Pd77.5Cu6Si16.5 metallic glass were cold drawn using diamond dies. A total area reduction of up to about 93% can be obtained after multiple passes through appropriate dies. After drawing two families of surface marking are observed: the traces of one set make an angle of about 41° to the wire axis while the other is nearly perpendicular to it. Tensile tests conducted on both drawn and undrawn wires show fracture on planes that always deviate from the 45° maximum shear plane. The fracture stresses of drawn wires are found to be slightly increased; the macroscopic elongation to break increases considerably after cold drawing. © 1979.
