ABSTRACT:
This invention relates to the production of large non-planar shapes of metallic glass fabricated from ribbon. The inventive method contemplates stacking the ribbon. The stacked ribbon is formed and held at temperatures of between 70 and 90% of the crystallization temperature for a time sufficient to facilitate permanent deformation of the stacked ribbons and to bond the ribbons.
