Description

Halbzeug und seine Verwendung  Semifinished product and its use
Die Erfindung betrifft ein band-, platten- oder blechförmiges Halbzeug umfassend einen partikelverstärkten Stahlwerkstoff sowie eine entsprechende Verwendung des The invention relates to a band-, plate- or sheet-shaped semi-finished product comprising a particle-reinforced steel material and a corresponding use of the
Halbzeugs. Semi-finished product.
Auf die Automobilhersteller lastet ein enormer Druck, die C02-Emissionen insbesondere bei Personenkraftwagen in den nächsten Jahren senken zu müssen, um nicht mit Geldstrafen belangt zu werden. Eine Möglichkeit, den C02-Ausstoß zu senken, besteht unter anderem durch eine Reduzierung des Fahrzeuggewichts. Aufgrund der steigenden Sicherheitsanforderungen kann auch nicht ausgeschlossen werden, dass zukünftig zusätzliche Teile bzw. Bauteile im Fahrzeug eingebaut werden müssen, um diesen Sicherheitsanforderungen gerecht zu werden, was wiederum im Widerspruch zur angestrebten Reduzierung des Gesamtgewichts des Fahrzeugs steht. Eine Möglichkeit, Gewicht einzusparen, ist beispielsweise die Karosserie, Rahmen und/oder das Fahrwerk eines Fahrzeugs noch leichter, durch leichte und innovative Werkstoffe im Vergleich zu den konventionell eingesetzten Werkstoffen zu gestalten bzw. zu bauen. So können beispielsweise bauteilspezifisch konventionelle Werkstoffe durch leichtere Werkstoffe mit vergleichbaren Eigenschaften ersetzt werden. Automotive manufacturers are under enormous pressure to cut C02 emissions, particularly in passenger cars, over the next few years in order to avoid fines. One way to reduce C0 2 emissions is by reducing vehicle weight, among other things. Due to the increasing safety requirements, it can not be ruled out that additional parts or components will have to be installed in the vehicle in future in order to meet these safety requirements, which in turn contradicts the intended reduction in the total weight of the vehicle. One way to save weight, for example, the body, frame and / or the chassis of a vehicle even easier to design and build by lightweight and innovative materials compared to the conventionally used materials. For example, component-specific conventional materials can be replaced by lighter materials with comparable properties.

gleichbleibenden Eigenschaften dünner ausgelegt werden als konventionelle Stähle und durch die Reduzierung der Materialdicke kann positiv Einfluss auf das Gesamtgewicht des Bauteils respektive des Fahrzeugs genommen werden. Derartige Stahlwerkstoffe eignen sich hervorragend für die Automobilindustrie. Gattungsgemäße Stahlwerkstoffe sind im Stand der Technik bekannt und ein Ausführungsbeispiel ist in der europäischen Offenlegungsschrift 2 703 509 offenbart. be designed thinner than conventional steels and by reducing the material thickness can be positively influenced on the total weight of the component or the vehicle. Such steel materials are ideal for the automotive industry. Generic steel materials are known in the art and one embodiment is disclosed in European Laid-Open Application 2 703 509.
Die Herstellung von partikelverstärkten Stahlwerkstoffen mit in der Stahlmatrix fein dispergierten Partikeln ist ebenfalls der Fachwelt bekannt (vgl. auch EP 2 703 509 AI). Auf die Verteilung der Partikel innerhalb der Stahlmatrix kann nur bedingt oder mit hohem Aufwand Einfluss genommen werden, so dass nicht ausgeschlossen werden kann, dass sich die Partikel auch oberflächennah bzw. direkt an/auf der Oberfläche während des Herstellungsprozesses absetzen bzw. festsetzen. Die eingesetzten Partikel sind in der Regel härter als der Matrixwerkstoff, so dass es im Zuge der Fertigung zum Endprodukt dazu kommen kann, dass die harten Partikel aus der Oberflächenebene der Stahlmatrix herausragen, wodurch die formgebenden Werkzeuge, beispielsweise im Stahlwerk bei der Herstellung als auch im Presswerk bei der Weiterverarbeitung, im Bereich der Kontaktierung schneller verschleißen können bzw. einem hohen abrasiven Verschleiß unterliegen. The production of particle-reinforced steel materials with particles finely dispersed in the steel matrix is likewise known to the experts (see also EP 2 703 509 A1). On the distribution of the particles within the steel matrix can be influenced only conditionally or with great effort, so that are not excluded It is also possible for the particles to settle or settle near the surface or directly on / on the surface during the production process. The particles used are generally harder than the matrix material, so that in the course of manufacturing the final product may occur that the hard particles protrude from the surface plane of the steel matrix, whereby the forming tools, for example in the steelworks in the production as well as in Press shop during further processing, can wear out faster in the area of contacting or be subject to high abrasive wear.
Aufgabe der vorliegenden Erfindung ist es, ein Halbzeug aus einem partikelverstärkten Stahlwerkstoff zur Verfügung zu stellen, mit welchem der abrasive Verschleiß an den formgebenden Werkzeugen im Wesentlichen verringert, insbesondere verhindert werden kann, sowie eine entsprechende Verwendung des Halbzeugs anzugeben. The object of the present invention is to provide a semifinished product made of a particle-reinforced steel material with which the abrasive wear on the shaping tools can be substantially reduced, in particular prevented, and a corresponding use of the semifinished product can be specified.

Zur Verstärkung des Stahlwerkstoffs kommen alle geeigneten Partikel, insbesondere keramische Partikel beispielsweise SiC-, A1203-, TiC-, Zr02 und/oder TiB2-Partikel, einzeln oder in The inventors have found that by providing at least one layer of a non-particle-reinforced metal material, which is fully or materially bonded to the particle-reinforced steel material on one or both sides, it can be ensured that no particles are present in the near-surface region and that the at least one layer from a non-particle-reinforced metal material assumes the function of a barrier and / or protective layer.

According to a first embodiment of the semifinished product according to the invention, the at least one layer of the non-particle-reinforced metal material has a
Materialdicke zwischen 0,2 % und 20 %, insbesondere zwischen 0,5 % und 15 % bezogen auf die Gesamtmaterialdicke des Halbzeugs auf. Der als Sperr- und/oder Schutzschicht vorgesehene nichtpartikelverstärkte Metallwerkstoff sollte in der Materialdicke derart bemessen sein, das zum Einen die Eigenschaften des Material thickness between 0.2% and 20%, in particular between 0.5% and 15% based on the total material thickness of the semifinished product. The intended as a barrier and / or protective layer non-particle-reinforced metal material should be sized in the material thickness, on the one hand, the properties of
partikelverstärkten Stahlwerkstoffs im Wesentlichen nicht negativ beeinflusst werden, wobei die Materialdicke der mindestens einen Lage maximal 20 %, insbesondere maximal 15 %, vorzugsweise maximal 10 % bezogen auf die Gesamtmaterialdicke des Halbzeugs beträgt, und zum Anderen zu gewährleisten, dass die Partikel im The material thickness of the at least one layer is at most 20%, in particular at most 15%, preferably at most 10% based on the total material thickness of the semifinished product, and on the other hand to ensure that the particles
