Abstract
Official abstract text for this publication.
Bulk metallic articles having a high-aspect ratio that are formed of bulk metallic glass, that are net-shaped and that are produced under process conditions that maximize the quality and integrity of the parts as well as the life of the mold tool, thus minimizing production costs, and manufacturing methods for producing such articles are provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an amorphous metal article comprising: providing a blank from a bulk metallic glass; heating the blank from the glass state to a processing temperature above the crystallization temperature, T x , but below the melting temperature, T m , of the bulk metallic glass, wherein the bulk metallic glass is heated substantially uniformly throughout the blank at a heating rate of at least 100° C./s to a the processing temperature wherein t…
