Claim:
1. A method of rapidly heating and shaping a metallic glass using a rapid capacitor discharge comprising: providing a sample of metallic glass, the sample having a substantially uniform cross-section; discharging a quantum of electrical energy of at least 50 Joules through the sample to heat the sample at a rate of at least 500 K/sec to a processing temperature between the glass transition temperature of the metallic glass and the equilibrium melting point of the metallic glass-forming alloy; where an electric field produced by the discharged quantum of electrical energy has an electromagnetic skin depth larger than a characteristic dimension of the sample; applying a deformational force to shape the heated sample into a metallic glass article; and cooling the metallic glass article to a temperature below the glass transition temperature of the metallic glass.
