摘要：
A method for superplastically forming a preform to manufacture a structural assembly with a contoured configuration is provided. The preform includes first and second structural members in a stacked configuration, with at least one additional peripheral member abutting the stack and joined thereto by a friction welded butt joint. In some cases, the preform defines dissimilar forming characteristics throughout, such as variations in material or thickness according to the amount of superplastic forming to be performed in each portion of the preform.
