摘要： The structure and the process for making a metallic sandwich structure in which metal worksheets, preferably made from titanium alloy, are joined in a preselected pattern by an intermittent or discontinuous weld. The joined sheets are sealed by a continuous weld to form an expandable envelope. Application of inert gas pressure to the envelope in a limiting fixture superplastically produces the sandwich structure as the expanded structure diffusion bonds to itself or other worksheets. Core configuration of the structure is determined by the intermittent weld pattern. Face sheets of the sandwich structure may be formed from one sheet of the envelope or may be inserted in the limiting fixture and the envelope expanded against the face sheets. Additionally, the face sheets may be preformed or formed concurrently with the core to produce the desired core and sandwich shape in a single operation.

摘要： The process for forming a metallic sandwich structure having a curved surface, particularly a surface curving about more than one axis, such as a quadric surface partially by direct displacement and partially by a fluid interface. Additionally, means to restrain the work sheets being formed with respect to the shaping fixture which allow a portion of the work sheets to flow into the forming cavity before absolute restraint is applied and the restraining means function independently of the clamping force of the press.
摘要翻译： 用于形成具有弯曲表面的金属夹层结构的方法，特别是围绕多于一个轴线弯曲的表面，例如部分通过直接位移部分地由流体界面弯曲的二次曲面。 此外，限制相对于成形夹具形成的工作片的装置，其允许一部分工作片在施加绝对约束之前流入成形腔，并且限制装置独立于压力机的夹紧力起作用。
