    摘要： Disclosed is an improved method of fabricating boron fiber and aluminum matrix composite structures, especially gas turbine compressor blades having titanium metal skins. Titanium skins and boron aluminum composite cores are preformed by gas pressure and hard dies prior to hot pressing. The composite sheets of the core are preformed with the use of expendable carrier sheets, which hold the stacked sheets firmly as both the carrier sheets and composites are shaped through moderate temperature and gas pressure against a hard die. The preforming permanently shapes and lightly bonds the composite sheets. The skins are preformed in an analogous process using gas pressurization of a metal envelope into die cavities. The skins and composite core are then hot pressed in hard dies to form the finished part.

    摘要： The present invention relates to a method of manufacturing formed aluminum components. The method comprises the steps: i. Providing a hollow profile of aluminum or aluminum allow, the profile having a predetermined length and comprising an outer wall having a pre-determined thickness; ii. Placing a hollow aluminum profile in a cavity of a bending tool and press bending the profile using the bending tool; and iii. Transferring the profile to a cavity of a forming tool and subjecting the interior of the profile to elevated gas pressure, whereby the section of the profile is distended until the outer wall of the profile abuts the forming tool, thereby providing a formed aluminum component; wherein the steps ii. and iii. are performed at a tool temperature of 350-470° C. The present invention further relates to formed aluminum components manufactured by such a method.

    摘要： A method of hydroforming a vehicle rail from an extruded aluminum tube includes the steps of positioning the extruded aluminum tube into a hydroforming die and partially closing the hydroforming die. Next is the step of applying a liquid under a first level of pressure to the extruded aluminum tube in the hydroforming die. This is followed by engaging an inner radius of a bend in the extruded aluminum tube with the hydroforming die before completely closing the hydroforming die and increasing the level of liquid pressure in the workpiece to a second level to form and hydro-pierce a part from the extruded aluminum tube.

    摘要： A method for manufacturing a part in the shape of a hollow profile is disclosed, with a hollow profile made of light metal being expanded by high internal pressure deformation. In order to be able to manufacture parts in the shape of hollow profiles based on light metals, even with high degrees of deformation, in simple fashion in a safe process, a sleeve made of a material with a greater ductility than the light metal, especially a steel material, is slid onto the hollow profile. The sleeve is located on the hollow profile in such fashion that a predetermined area of the hollow profile is covered that is to be deformed during subsequent expansion with a high degree of deformation that exceeds the expandability of the light metal. The hollow profile is expanded by expansion by high internal pressure within this predetermined area to a degree beyond the bursting limit, whereupon the sleeve alone is expanded, subjected directly to high internal pressure at the burst point in the final shaped hollow profile, until the final shape of the part is reached in the area that is covered by the sleeve that is held at both ends in a press fit against the hollow profile.
