摘要： A pre-coated plate of steel is heated in a furnace to form an intermetallic alloying layer on the plate at least in an area thereof. Air is pretreated through drying to produce dried air which is fed into the furnace to control the atmosphere within the furnace while the pre-coated plate is in the furnace.

摘要： A method for producing a motor vehicle component with at least two regions of different strengths and a protective layer, consisting of the following process steps: —providing precoated blanks made of a steel alloy, which can be hardened, —homogeneously heating to a heating temperature, which is at least greater than or equal to the AC1 temperature, preferably greater than or equal to the AC3 temperature, —holding the heating temperature, so that the precoating alloys with the blank, —homogeneously intercooling the alloyed blank to an intercooling temperature between 450 deg. C. and 700 deg. C., partially heating the blank from the intercooling temperature to at least the AC3 temperature in regions of the first type and holding regions of the second type at substantially intercooling temperature, —hot forming and press hardening the partially tempered blank so as to form the motor vehicle component, wherein a tensile strength of greater than 1400 MPa is produced in regions of the first type, a tensile strength of less than 1050 MPa is produced in regions of the second type, and a transition region is produced between said regions.

摘要： A method for producing a motor vehicle component includes the steps of providing a precipitation-hardenable blank composed of a 6000 or 7000 grade aluminum alloy, solution-annealing the blank at a temperature between 350° C. and 550° C. for a time period of 2 to 30 min., in particular 3 to 20 min. and preferably 5 to 15 min., in particular at a temperature between 440° C. and 480° C. in the case of a 7000 grade aluminum alloy, and in particular at a temperature between 490° C. and 545° C. in the case of a 6000 grade aluminum alloy, subjecting the solution-annealed blank to partially different quenching, a first region being quenched to a temperature between 150° C. and 250° C., and a further region being quenched to a temperature below 150° C., deforming the blank during or after the partially different quenching.
