ABSTRACT:
This invention relates to the production of large shapes of metallic glass fabricated from ribbon. The inventive method contemplates placing the ribbon and consolidating the alloy under a pressure or at least 1000 psi at a temperature of between 70% and 90% of the crystallization temperature for a time sufficient to facilitate bonding of the ribbons.
