摘要： The invention relates to a cost-effectively producible rim for a motor vehicle, comprising a wheel disc (3) manufactured from a steel plate and a rim strip (2) running peripherally around the wheel disc (3). The steel plate of the wheel disc (3) being comprised of at least three steel layers on top of one another and connected rigidly together by way of roll-bonding, the innermost core layer (6) of which having a lower strength than the outer layers (4,5), guarantees that the rim according to the invention can safely absorb the forces occurring in practical operation while being of low weight.

摘要： The invention relates to a method for producing a shaped sheet metal part from a blank or a semi-finished product (1) made of a material consisting of steel having at least 60 wt.% Fe and a residual austenitic content of at least 5%, wherein the blank or the semi-finished product (1) is partially cooled to a temperature of less than -20 °C prior to the shaping and is shaped at a temperature below -20 °C in a shaping die (2). The problem of providing a method to produce components appropriately designed in terms of load, which enables a highly technical application of low-temperature shaping and is designed in a particularly simple manner, is solved in that a reduction of the material temperature of the blank or the semi-finished product (1) takes place in a cooling device (3) maintained at a temperature below -20 °C.

摘要： The invention relates to a method for producing a metallic component (B), whereby adjacent regions (Z1, Z2, Z3) having different material properties can be produced on the metallic component (B) in a simple manner. According to said method, a sheet metal element (E) heated to a forming temperature is shaped in a form tool (1) into an end component (B). The form tool (1) comprises a tempering device for regulating the temperature of at least one of the sections (5,7,16) thereof that comes into contact with the sheet metal element (E) during the forming process. The forming speed is controlled in such a way that the component regions with the desired increased hardness come into contact with the cooled form tool faster than adjacent regions with the desired reduced hardness. The invention is especially suitable for shaping sheet metal elements of different thicknesses that are interconnected with a material fit (tailored blanks).
