Patent number: 10882106Abstract: Disclosed is a method for producing a composite material, wherein two or more composite components are arranged with respect to one another by casting to form a composite, so as to create a contact region essentially without a material bond between the composite components, wherein the composite components are thereafter materially bonded to one another in the contact region by means of a hot-rolling process.Type: GrantFiled: November 3, 2015Date of Patent: January 5, 2021Assignees: ThyssenKrupp Steel Europe AG, ThyssenKrupp AGInventors: Jens Ulrik Becker, Rüdiger Mempel, Stefan Myslowicki, Roland Wunderlich, Ralf Zemke

Patent number: 10525669Abstract: A method for producing a composite material, particularly a steel composite material, may involve providing a first workpiece and a second workpiece, producing a bonded connection between said first and said second workpiece in order to form a provisional composite, and rolling said provisional composite in order to form the composite material. During the rolling, the bonded connection may be at least partially released, in the form of a predetermined breaking point. The rolling may be performed as hot rolling. Further, the method may involve substantially hermetically sealing the provisional composite by way of a sealant. The first and second work pieces, moreover, may be peripherally connected by way of the bonded connection along an edge area of a contact surface formed by the first and second work pieces.Type: GrantFiled: February 23, 2016Date of Patent: January 7, 2020Assignees: THYSSENKRUPP STEEL EUROPE AG, THYSSENKRUPP AGInventors: Jens-Ulrik Becker, Rainer Klenn, Stefan Myslowicki, Roland Wunderlich

Publication number: 20180185954Abstract: A process may be used to produce a composite material in a rolling plant. The process may involve providing a first workpiece and a second workpiece, which workpieces are configured in the form of a temporary composite. The process may further involve producing a planar connection between the first and second workpieces in the temporary composite by prerolling. Still further, the process may involve rolling, in particular hot rolling, the temporary composite to form the composite material after the planar connection has been produced by prerolling. The process may also involve heating the temporary composite before and/or after the prerolling.Type: ApplicationFiled: June 16, 2016Publication date: July 5, 2018Applicants: THYSSENKRUPP STEEL EUROPE AG, thyssenkrupp AGInventors: Jens-Ulrik BECKER, Stefan MYSLOWICKI, Roland WUNDERLICH

Patent number: 9088011Abstract: A bipolar plate which can be produced particularly economically for a fuel cell, with which a high degree of efficiency is guaranteed over a long service life. The bipolar plate has a core layer consisting of a steel material, the surfaces of said core layer, which are associated with the respective electrolyte carriers of the fuel cell, having a corrosion protection layer, protecting the core layer against corrosion. The corrosion protection layers consist of a metal material and extend on both sides over the whole surface of the core layer. At the same time the corrosion protection layers are in turn coated over the whole surface with an electrically conductive functional coating, which is essentially entirely impermeable for the metal ions emerging from the core layer and/or the corrosion protection layers. The invention likewise relates to at least one fuel cell comprising a bipolar plate according to the invention.Type: GrantFiled: July 3, 2008Date of Patent: July 21, 2015Assignee: ThyssenKrupp Steel Europe AGInventors: Stefan Wischmann, Horst Walter Tamler, Roland Wunderlich, Michael Steinhorst, Krasimir Nikolov, Nicole Weiher, Jens-Ulrik Becker, Stefan Peter Puls, Bernd Schuhmacher

Patent number: 8535813Abstract: A use of a coilable multi-layer metallic composite material produced by means of roll-cladding in a vehicle structure, in particular a body structure, provides an alternative to monolithic materials. The composite material used in a vehicle structure is a lightweight composite material and comprises three layers of a steel alloy, wherein at least one of the layers is formed from a high-strength or very high-strength steel alloy.Type: GrantFiled: April 27, 2009Date of Patent: September 17, 2013Assignee: ThyssenKrupp Steel Europe AGInventors: Jens-Ulrik Becker, Lothar Patberg, Peter Seyfried, Horst Walter Tamler, Roland Wunderlich

Patent number: 8491063Abstract: The invention relates to a wheel rim for a motor vehicle which can be economically manufactured, with a wheel disc made of steel sheet and a rim flap running around the circumference of the wheel disc. Due to the fact that the steel sheet of the wheel disc is formed from at least three superimposed steel layers, joined to one another by roll-bonding in a non-detachable manner, of which the inner core layer has a lower strength than the outer layers, it is thereby guaranteed that the wheel rim according to the invention, with a low weight, can safely accommodate the forces arising in practical operation.Type: GrantFiled: September 21, 2009Date of Patent: July 23, 2013Assignee: ThyssenKrupp Steel Europe AGInventors: Günter Stich, Horst Walter Tamler, Jens-Ulrik Becker, Thomas Heller, Roland Wunderlich

Patent number: 8221898Abstract: A multilayered composite part includes a plurality of steel alloy layers connected to one another, with at least one core layer consisting of a soft, well deformable steel alloy and at least one steel alloy layer of a very high strength steel alloy, arranged on the core layer. A multilayered composite part which is characterized simultaneously by a high strength paired with very good outer skin quality and very good paint adherence, is achieved in that at least one outer steel alloy layer of a soft, well deformable steel alloy is provided on the very high strength steel alloy layer.Type: GrantFiled: April 25, 2008Date of Patent: July 17, 2012Assignee: ThyssenKrupp Steel Europe AGInventors: Jens-Ulrik Becker, Peter Seyfried, Michael Steinhorst, Horst Walter Tamler, Roland Wunderlich
