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.
Claims6
A method for making bulk samples from metallic glass ribbons comprising:
- stacking aligned ribbons in an overlapping parallel relationship;
- forming said stacked ribbons to a non-planar configuration;
- and
- holding said formed stacked ribbons at a pressure of at least 1000 psi (6895 kPa) at a temperature between about 70 and 90% of the crystallization temperature for a time sufficient to provide permanent deformation of said stacked deformed ribbons and to bond the ribbons together.
