ABSTRACT:
Compression diffusion bonding according to the present invention uses a CRES template to apply increased pressure in the areas designated for diffusion bonds (DB) to improved the bond quality and to reduce the processing time. The CRES template is patterned to correspond with the DB arrangement in the superplastically formed part. The forming press forces the template against the pack of SPF sheets to provide 300-1200 psi or more pressure along the bond lines to speed their formation.
