ABSTRACT:
Multisheet SPF parts with braze joints at selected locations are produced with improved energy efficiency and at lower cost. The parts include a core defined with intermittent welds between two or more core sheets and aerodynamically smooth facing sheets brazed to the core. The manufacturing process includes heating the multisheet pack to its superplastic forming range below the melting point of the braze alloy, superplastically forming the pack to define braze joints having unmelted braze alloy; increasing the temperature to the braze temperature of the braze alloy, and cooling the pack below the superplastic range to freeze the braze alloy in the braze joint.
