Automated rapid discharge forming of metallic glasses

摘要

An automated rapid capacitive discharge apparatus is provided for sequentially or simultaneously rapidly heating and shaping a plurality of metallic glass feedstock samples. The apparatus includes a sample feeder defining a body for holding a plurality of samples and being capable of sequentially positioning at least one feedstock sample into a discharge position within the processing compartment. In the processing compartment the sample is heated by a discharge of a quantum of electrical energy supplied via electrodes, then shaped into a desired shape by means of a shaping tool, and subsequently moved out of the discharge position as a second feedstock moves into a discharge position.

主权项

1. A rapid discharge heating and forming apparatus comprising:
at least one sample feeder configured to hold a plurality of feedstock samples, the at least one sample feeder configured to sequentially position at least one of the plurality of feedstock samples at a discharge position within at least one feedstock chamber, at least one pair of two electrodes interconnected to a source of electrical energy, each one of a pair of electrodes disposed at an opposing end of the feedstock sample and the electrodes configured to electrically connect to the feedstock sample at the discharge position and heat the feedstock sample at the discharge position; and a shaping tool configured to shape the heated feedstock sample to form an amorphous article.
