摘要： A bi-metallic component including a tubular stud member extending from an open first end to an open second end, and a cast member cast around the open second end of the tubular stud member is provided. The cast member is formed from first material, such as an aluminum alloy; and the tubular stud member is formed from a second material, such as steel. The tubular stub member has an interior surface which sealingly receives a removable core member for preventing molten first material from flowing through the stub member between the open ends thereof during casting of the cast member around the second end. The bi-metallic component can be used in a variety of automotive applications, for example in a cradle, frame, twist axle, control arm, door pillar, instrument panel support, or bumper assembly.

摘要： In a method for producing hot-rolled sections of steel with a rectangular or square cross-section, a substantially round pipe blank produced seamlessly by hot rolling or cold finished and welded and having a defined nominal outside diameter is initially produced and then formed at a forming temperature into a hollow section having the required cross-section, with visible edges C1 and C2 of the hollow section having a value ≦1.5×t (t=wall thickness). The pipe blank has a nominal outer diameter determined from a reduction ratio of the pipe blank to be achieved and the hollow section dimensions to be achieved, wherein the reduction ration lies within a range of −2% to −13% and is determined according to the following formula: Reduction ratio R[%]=[(2×(H+B))−π×D]×100%/[2×(H+B)].

摘要： A method of forming metal castings, including positioning a first end of a structural member in a first mold cavity and a second end of the structural member in a second mold cavity. The first and second mold cavities being fluidly coupled to a reservoir of molten metal. Applying a main pressure to the molten metal in the reservoir to force the molten metal into the first mold cavity and the second mold cavity. Then, applying a first auxiliary pressure to the first mold cavity and a second auxiliary pressure to the second mold cavity to densify the casting formed in the first mold cavity and the second mold cavity. Also, a method for casting including maintaining a main pressure at or less than an initial, mold-filling pressure after first and second mold cavities have been filled. Additionally, a method for detecting whether a first mold cavity is sufficiently filled with molten metal by monitoring a moveable element.
