Title:
HIGH-DUCTILITY NANO-PARTICLE DISPERSION METALLIC GLASS AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2000/032833
Kind Code:
A1
Abstract:
A production method for bulk metallic glass which has a high ductility at a cold drawing ratio of at least 70%, better mechanical characteristics after cold drawing than as-cast one and high reliability, and which comprises the step of pressing molten metal consisting of an alloy composition having a metallic glass forming capability between a die and a punch constituting a high thermal-conductivity water-cooled forming die so as to apply a pressurizing force onto the molten metal and solidify it while pressure-drawing, thereby obtaining bulk metallic glass having nano-particles dispersed in an amorphous phase. A product made by cold-drawing the high-ductility nano-particle dispersion metallic glass.
