Abstract
Disclosed is a composite metal structure of a desired configuration and a method of fabricating the composite metal structure by preshaping at least one metal layer prior to assembly of the metal layers in a die of a second preshape configuration. Following brazing of the metal layers while in the die, the brazed structure is removed from the die and springs to the final desired configuration. The process has proved to be particularly useful in fabricating composite electron beam targets for use in X-ray scanners.
