Abstract: Turbochargers include a compressor comprising a compressor body extending from a compressor back face and a plurality of blades extending from the compressor body, a turbine comprising a turbine body extending from a turbine back face and a plurality of blades extending from the turbine body, and a shaft coupled at a first end to the compressor back face and at a second end to the turbine back face. The shaft includes an internal passage extending from the first end towards the second end in fluid communication with the compressor blades and one or more fans disposed within the internal passage and configured to draw air toward the second end of the shaft. The internal passage of the shaft is in fluid communication with the compressor blades via one or more bleed air passages, which can be biased towards an outer diameter of the compressor body.

Abstract: A panel assembly is formed by a plurality of bonds between two sheet materials in a face to face relationship to form a preform. The plurality of bonds define a closed perimeter region between the two sheet materials and an open perimeter region between the two sheet materials. The preform may be formed into a predefined shape. Pressurized fluid is applied through an inlet into the open perimeter region to expand the preform. The pressurized fluid expands the open perimeter region such that the two sheet materials expand in an opposing direction, thereby defining an expanded open perimeter region. The closed perimeter region between the two sheet materials remains vacant of the pressurized fluid such that the closed perimeter region is not expanded. The expanded open perimeter region is filled with a filler material for improving a performance characteristic of the panel assembly, e.g., strength, sound absorption, or stiffness.

Abstract: An integrally formed piston has a crown portion having an upper crown surface and an undercrown surface. A ring belt extends from the undercrown surface at a periphery thereof. The ring belt includes an uppermost ring land and at least one oil galley contoured to extend around at least two surfaces of the uppermost ring land. The oil galley has an opening at the undercrown surface for receiving a cooling fluid therein for cooling the uppermost ring land. A skirt extends from the undercrown surface and the ring belt and has a plurality of stiffening features arranged in a truss formation. At least one of the plurality of stiffening features has an I-beam cross-section and another of the plurality of stiffening features has a negative draft angle.

Abstract: A method of resistance spot welding a workpiece stack-up that includes an aluminum workpiece and an overlapping adjacent steel workpiece so as to minimize the thickness of an intermetallic layer comprising Fe—Al intermetallic compounds involves providing reaction-slowing elements at the faying interface of the aluminum and steel workpieces. The reaction-slowing elements may include at least one of carbon, copper, silicon, nickel, manganese, cobalt, or chromium. Various ways are available for making the one or more reaction-slowing elements available at the faying interface of the aluminum and steel workpieces including being dissolved in a high strength steel or being present in an interlayer that may take on a variety of forms including a rigid shim, a flexible foil, a deposited layer adhered to and metallurgically bonded with a faying surface of the steel workpiece, or an interadjacent organic material layer that includes particles containing the reaction-slowing elements.

Abstract: Processes for forming blanks having tailored properties in localized areas are provided. The blanks are then formed into three-dimensionally shaped components (e.g., high-strength automotive parts). A sheet of high-strength metal alloy may be selectively heated in a first region to a temperature below a melting point of the metal alloy with a heat source, while a second region of the sheet adjacent to the first region remains unheated. The selective heating creates a first region of the metal alloy having at least one material property distinct from the second region. After the sheet is cut to form a blank, the blank comprises a portion of the first region and a portion of the second region. In this manner, a plurality of distinct tailored regions may be formed on each blank. The process may be continuous or semi-continuous and further include cutting of blanks from the sheet. High-strength structural components are also provided.
