ABSTRACT:
A method of rapidly solidifying thin metallic strips, comprising projecting a jet of molten metal or alloy under reduced atmospheric pressure onto a cold substrate moving at high speed, thereby forming the strip in contact with the substrate, and then bringing the strip rapidly into higher atmospheric pressure. Forming the strip on the substrate under reduced atmospheric pressure improves the quality of the edges and surface of the strip, while bringing the strip rapidly into higher atmospheric pressure improves the adherence of the strip to the substrate. If the strip is brought into higher atmospheric pressure before its temperature falls to the temperature of vitrification, the properties of the vitreous metal formed, including its ductility, are also improved, because of the more rapid passage through the temperature range above the vitrification temperature than if the metal were cooled under reduced pressure.
