| 20120097298 | METHOD FOR PRODUCING PARTIALLY HARDENED STEEL COMPONENTS - The invention relates to a method for producing partially hardened steel components in which a blank is subjected to a temperature increase that is sufficient for a quench-hardening and after reaching a desired temperature, the blank is transferred to a forming tool in which the blank is quench-hardened or the blank is cold-formed and the component obtained by the cold-forming is then subjected to a temperature increase. During the heating of the blank or component, absorption masses rest against and/or are spaced with a small gap apart from regions that are intended to have a lower hardness and/or higher ductility; with regard to its expansion and thickness, its thermal conductivity, and its thermal capacity and/or with regard to its emissivity, the absorption mass is dimensioned so that the thermal energy acting on the component in the region to remain ductile flows through the component into the absorption mass. | 04-26-2012 |

| 20130160906 | METHOD FOR PRODUCING A MOTOR VEHICLE COMPONENT AND MOTOR VEHICLE COMPONENT - A method for producing a motor vehicle component having two regions, with different strength is disclosed. A first one of the two regions has a high strength and a second one of the two regions has a higher ductility and lower strength relative to the first region. In a motor vehicle component produced with the method, the first region has a strength between 1400 and 1600 MPa at a breaking elongation A5>13% and the second region has a tensile strength between 950 and 1050 MPa at a breaking elongation A5>16%. | 06-27-2013 |

| 20140083572 | FURNACE SYSTEM FOR THE CONTROLLED HEAT TREATMENT OF SHEET METAL COMPONENTS - The invention relates to a furnace system and a method for the controlled heat treatment of sheet metal components in individual component zones. The invention proposes a furnace system that is suitable for partly heating components made of steel sheet to a temperature above the AC3 temperature. The furnace system has a production furnace for heating the steel sheet parts to a temperature that is close to but below the AC3 temperature, said furnace system further having a profiling furnace with at least one level. The at least one level has an upper and a lower part and a product-specific intermediate flange that is introduced into a corresponding receiving area. The product-specific intermediate flange is designed to impose a specified temperature profile on the component with temperatures over AC3 for regions to be hardened and below AC3 for softer regions. Furthermore, the invention relates to a corresponding method for partly heating steel sheet parts to a temperature above the AC3 temperature. | 03-27-2014 |

| 20120090741 | METHOD FOR PRODUCING A HOT-FORMED AND PRESS-HARDENED METAL COMPONENT - The present invention relates to a method for producing a hot-formed and press-hardened metal component for an automobile having at least two regions of different hardness. A hardenable sheet-metal blank is heated to at least an austenizing temperature and a first region of the sheet-metal blank is intermediately cooled at a cooling speed greater than the lower critical cooling speed of the material of the sheet-metal blank. The sheet-metal blank is then hot-formed and press-hardened in a press-hardening tool by quenching the first region from a bainitic structure transformation stage, thereby adjusting a mixed structure of martensite and bainite in the first region. | 04-19-2012 |
| 20130180633 | Method of Manufacturing Multi Physical Properties Part - A multi physical properties part used in automotive components required to be lightweight and provide collision safety, and a method of manufacturing a multi physical properties part, in which the multi physical properties part may be more economically and simply manufactured by using two or more separated die sets without using an additional heating device or treating a die surface. A method of manufacturing a multi physical properties part, which includes positioning a single heated formed article in two or more die sets, and then manufacturing a multi physical properties part including two or more regions having different physical properties by differing cooling conditions in the respective die set. | 07-18-2013 |
| 20150090377 | STEEL SHEET FOR HOT PRESSING USE, PRESS-FORMED PRODUCT, AND METHOD FOR MANUFACTURING PRESS-FORMED PRODUCT - A steel sheet for hot pressing use according to the present invention has a specified chemical component composition, wherein some of Ti-containing precipitates contained in the steel sheet, each of which having an equivalent circle diameter of 30 nm or less, have an average equivalent circle diameter of 6 nm or less, the precipitated Ti amount and the total Ti amount in the steel fulfill the relationship represented by formula (1) shown below, and the sum total of the fraction of bainite and the fraction of martensite in the metal microstructure is 80 area % or more. | 04-02-2015 |
