Abstract
A method of extruding a glassy aluminum-based alloy billet, by soaking the billet for sufficient time to heat the billet to an extrusion starting temperature of from about 300° F. to about 600° F. and extruding the billet in a streamline die having an extrusion ratio to keep the adiabatic temperature below the starting temperature while maintaining the streamline die at a temperature of about 400° F. to about 600° F. at a ram speed less than that which would raise the streamline die temperature within this range.
