    摘要: In one embodiment a method to join a first structure to a second structure, comprises aligning a first hole in the first structure with a second hole in the second structure and inserting a fastener into the first hole and the second hole. The fastener comprises a shape memory alloy which was formed into a first shape having a diameter slightly larger than a diameter of the first hole and the second hole when the shape memory alloy was in an austenite state and reduced to a second shape having a diameter less than the diameter of the first hole and the second hole when the shape memory alloy was in a martensite state. The method further comprises heating the fastener above an austenite start transition temperature, such that the fastener initiates free expansion from the second shape back to the first shape and establishes physical contact with the surface of the first hole and the second hole and continuing to heat the fastener such that first structure and the second structure proximate the holes and the fastener undergo plastic deformation.

    摘要: A method and apparatus for forming a workpiece having a desired configuration as well as an associated preform assembly are provided. The forming method and apparatus as well as the preform assembly include a hydrostatic pressing medium, such as a layer of glass, disposed within the die cavity proximate to at least one side of the workpiece. The hydrostatic pressing medium is configured to have a relatively low viscosity at the temperatures at which the workpiece is processed, thereby facilitating the relatively even application of pressure to the workpiece. As such, a workpiece having a complex configuration may be formed utilizing a single acting die.
