Abstract
A rapid discharge heating and forming apparatus is provided. The apparatus includes a source of electrical energy and at least two electrodes configured to interconnect the source of electrical energy to a metallic glass sample. The apparatus also includes a shaping tool disposed in forming relation to the metallic glass sample. The source of electrical energy and the at least two electrodes are configured to deliver a quantum of electrical energy to the metallic glass sample to heat the metallic glass sample. The shaping tool is configured to apply a deformational force to shape the heated sample to an article. The at least two electrodes have a yield strength of at least 200 MPa, a Young's modulus that is at least 25% higher than the metallic glass sample, and an electrical resistivity that is lower than the metallic glass sample by a factor of at least 3.
