Method for producing a shaped component having at least two structural regions of different ductility

A method of producing a shaped component with at least two structural regions of different ductility, comprising the steps of:

• cutting a blank from a strip material of high-strength boron steel provided with an Al/Si coating;
• heating the blank in a first temperature zone of a furnace to a first temperature of about 830° C.-950° C.;
• maintaining the blank at the first temperature for a defined time;
• allowing a first region of the blank to cool down in a second temperature zone of the furnace to a second temperature of about 550° C.-700° C.;
• maintaining the first region of the blank at the second temperature for a defined time, while maintaining a second region of the blank in a third temperature zone of the furnace at the first temperature;
• and
• forming the blank into the shaped component in a thermoforming process.

A method of producing a shaped component with at least two structural regions of different ductility, comprising the steps of:

• heating a strip material of high-strength boron steel provided with an Al/Si coating in a pre-furnace to a first temperature of about 830° C.-950° C.;
• maintaining the strip material at the first temperature for a defined time;
• cooling down the strip material;
• cutting blanks from the strip material;
• transferring each blank into a two-zone furnace;
• heating a first region of each blank in a first zone of the furnace to a second temperature of about 550° C.-700° C., while heating a second region in a second zone of the furnace to the first temperature;
• and
• forming the blanks into the shaped component in a thermoforming process.
