Consolidation of the Cu46Zr42Al7 Y5 amorphous ribbons and powder alloy by hot extrusion

The amorphous Cu46Zr42Al7Y5 alloy presents large supercooled liquid region (∆TX = 100 K), with a viscosity of about 106 N.s/m2 where the material can flow as a liquid, making it possible an easy deformation in this temperature region. The aim of this work was to analyze processing routes to produce...
