摘要： A method is provided for controlling the strain rate during superplastic forming of a blank of material into a part. The method produces a part in a minimum time by deforming the material under suitable-optimum superplastic conditions. A relationship is determined between time and the pressure required to form the blank against the configured surface of a die at a strain rate which causes the blank to flow superplastically. The blank is positioned in the die and held at a temperature at which the material exhibits superplasticity. Pressure is applied to the blank in accordance with the previously determined relationship between time and pressure until the part is formed.

摘要： A pressure forming device comprises a liquid pressure chamber which communicates with a mold-forming member having a mold cavity into which an article to be formed is inserted. A plunger is mounted for sliding sealing movement in respect to a wall bounding or communicating with the pressure chamber so that it may be moved rapidly in an impulsive movement to displace liquid of the chamber against the member to be molded in the mold cavity to form it to the configuration of the cavity. Means are provided for regulating the movement of a hammer to strike the plunger member to move it in an impulsive movement, and various means are shown for the construction of a mold cavity member and for the means in holding the member to be molded to permit its selected deformation.

摘要： A method is disclosed for removing a part from a die, the part having been produced by clamping a preform between first and second dies and forming at least a portion of the preform into a cavity of the first die. The method comprises the steps of drawing a vacuum from between at least a portion of the formed preform and the second die and separating the second die from the first die such that the part is withdrawn from the cavity of the first die. In a preferred embodiment, wherein the part is clamped abouts its periphery, the method involves the additional steps of providing a channel about at least a portion of the second die aligned with and in communication with the periphery of the preform, and providing sealing members to seal off the channel. The vacuum is then drawn from the channel.

摘要： In a weld for two metals having adjacent surfaces with a welded zone having deposited weld metal and an unwelded zone with a stress concentration between the two zones that would normally drastically decrease the fatigue strength, the fatigue strength is greatly improved by applying a preliminary load on the welds zone by the application of a fluid pressure between the unwelded adjacent surfaces to directly stress the stress concentration transition area. Preferably, the stress intensity factor for the fluid pressure at the stress concentration zone will be higher than the combined tensile and flexural stress intensity factors so that there will be localized yielding at the stress concentration area without damaging the remainder of the weld. The metal and/or fluid is heated to avoid fracture and further to vaporize any liquid remaining once the fluid pressure is removed.
