Abstract
Description
Die Erfindung betrifft eine Aluminiumlegierung zur Herstellung von Wärmeabschirmblechen mit einem Legierungsanteil von Aluminium größer als 97%.The invention relates to an aluminum alloy Manufacture of heat shields with one Alloy content of aluminum greater than 97%.
Aufgrund der für eine Wärmeabschirmung besonders vorteilhaften physikalischen Eigenschaften von Aluminium - hoher Reflektionsgrad im Infrarot-Bereich und sehr gute Wärmeleitfähigkeit - haben sich Aluminiumlegierungen als Werkstoff zur Herstellung von Wärmeabschirmblechen als Standardlösung durchgesetzt. Um die genannten physikalischen Eigenschaften des Aluminium umfangreich zu nutzen und den hohen Anforderungen an die Umformbarkeit des Werkstoffes bei der Herstellung von Wärmeabschirmblechen gerecht zu werden, werden zur Zeit etwa 80% der Wärmeabschirmbleche in Al 99,5 (AA1050) gefertigt. Eine hinreichend gute Umformbarkeit dieses Werkstoffs durch Tiefziehen ist gewährleistet, da die Dehnung (A5) von Al 99,5 bei etwa 45% liegt.Because of the special for a heat shield advantageous physical properties of aluminum - high degree of reflection in the infrared range and very good Thermal conductivity - have become aluminum alloys Material for the production of heat shielding sheets as Standard solution enforced. To the above physical properties of aluminum use and the high demands on formability of the material in the manufacture of Heat shields are currently being used about 80% of the heat shielding plates in Al 99.5 (AA1050) manufactured. A sufficiently good formability of this Material by deep drawing is guaranteed because the Elongation (A5) of Al 99.5 is about 45%.
Nach DIN weist Al 99,5 neben Aluminium folgende
Legierungsanteile in den angegebenen Grenzen auf:
Die Verwendung von Al 99,5 ist zwar unter den Gesichtspunkten hohe Wärmeabschirmung und hohe Umformbarkeit vorteilhaft, gleichzeitig jedoch unter verschiedenen anderen Aspekten problematisch. Zum einen weist Al 99,5 eine geringe Festigkeit auf. Beim Einsatz von Wärmeabschirmblechen im Kraftfahrzeugbau werden jedoch erhebliche Anforderungen an die Festigkeit gestellt, die sich beispielsweise aus den Einwirkungen des Fahrtwindes oder von Spritzwasser bei hohen Geschwindigkeiten sowie der Einwirkung von Steinschlag ergeben. Die geringe Festigkeit von Al 99,5 führt dazu, daß zur Gewährleistung der erforderlichen Festigkeit Blechformteile mit größerer Dicke eingesetzt werden müssen, was einerseits die Kosten erhöht und andererseits das Gewicht des Wärmeabschirmbleches vergrößert. Die geringe thermische Stabilität von Al 99,5 - Kriechen setzt bereits bei Temperaturen von über 150 °C ein - führt zu einer im Einsatz geringen Formstabilität, die jedoch zur Einhaltung der Abstände des Wärmeabschirmbleches gegenüber beispielsweise einem Katalysator und einem Fahrzeugunterboden zur Gewährleistung der erwünschten Wärmeabschirmung notwendig ist. Al 99,5 weist aufgrund der hohen Dehnungswerte, wie bereits erwähnt eine gute Tiefziehbarkeit auf. Die Dehngrenze ist mit etwa 30 N/mm2 jedoch gering. Die geringe Dehngrenze von Al 99,5 begrenzt die Möglichkeiten während des Umformprozesses bei der Herstellung von Wärmeabschirmblechen.The use of Al 99.5 is advantageous from the point of view of high heat shielding and high formability, but at the same time is problematic from various other aspects. On the one hand, Al 99.5 has a low strength. When using heat shields in motor vehicle construction, however, considerable demands are placed on the strength, which result, for example, from the effects of the wind or spray water at high speeds and the impact of stone chips. The low strength of Al 99.5 means that sheet metal parts with a greater thickness have to be used to ensure the required strength, which on the one hand increases the costs and on the other hand increases the weight of the heat shielding plate. The low thermal stability of Al 99.5 - creep already starts at temperatures of over 150 ° C - leads to a low dimensional stability in use, which however means that the distances between the heat shielding plate and that of a catalytic converter and a vehicle underbody, for example, to ensure the desired heat shielding are maintained necessary is. As already mentioned, Al 99.5 has good deep-drawing properties due to the high elongation values. The yield strength is, however, low at around 30 N / mm 2 . The low proof stress of Al 99.5 limits the possibilities during the forming process in the manufacture of heat shielding plates.
Ein weiteres Problem insbesondere im Dauereinsatz von Wärmeabschirmblechen besteht darin, daß Al 99,5 eine hohe Neigung zur Grobkornbildung insbesondere nach geringen Kaltumformungen aufweist. Diese Grobkornbildung, insbesondere bei der zwangsläufigen thermischen Belastung von Wärmeabschirmblechen, führt dazu, daß speziell in Radien die Gefahr einer Rißentstehung beispielsweise in Befestigungspunkten des Wärmeabschirmbleches besteht. Another problem, especially in the continuous use of Heat shielding is that Al 99.5 is high Tendency to coarse grain formation, especially after small Cold forming has. This coarse grain formation, especially with the inevitable thermal load of heat shields, leads to the fact that especially in Radii the risk of cracking, for example in Fastening points of the heat shield plate.
Auch sind die dynamischen Lastaufnahmen von aus Al 99,5 gefertigten Wärmeabschirmblechen aufgrund der starken Grobkornbildung unzureichend. Die aus strukturellen Gründen an sich erwünschte Verwendung von Noppenblechen ist in Verbindung mit dem Einsatz von Al 99,5 problematisch, da eine Formstabilität nicht gewährleistet werden kann. Diese Formstabilität wird dadurch beeinträchtigt, daß bei Noppenblechen an den umgeformten Noppenbereichen mit einer verstärkten Grobkornbildung nach einer Wärmebelastung gerechnet werden muß.The dynamic load pick-ups are made of Al 99.5 manufactured heat shields due to the strong Coarse grain formation insufficient. The structural Reasons to use knobbed sheets, which is desirable per se is in connection with the use of Al 99.5 problematic, since dimensional stability is not guaranteed can be. This ensures this dimensional stability impaired that with knobbed sheets on the formed Knob areas with increased coarse grain formation must be expected after a heat load.
Ausgehend von dem zuvor beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Aluminiumlegierung zur Verfügung zu stellen, die gegenüber Al 99,5 eine weiter verbesserte Umformbarkeit, eine verbesserte Festigkeit, eine höhere thermische Stabilität und eine geringere Neigung zur Grobkornbildung aufweist.Starting from the prior art described above the invention is based on the object To provide aluminum alloy that a further improved formability compared to Al 99.5, improved strength, higher thermal Stability and less tendency to form coarse grains having.
Erfindungsgemäß ist die zuvor hergeleitete und aufgezeigte Aufgabe dadurch gelöst, daß die Summe der Legierungsanteile von höchstens zwei Hauptlegierungskomponenten die Summe der Legierungsanteile der Restlegierungskomponenten um mindestens den Faktor 5 übersteigt. Durch die erfindungsgemäße Übergewichtung von höchstens zwei für Al 99,5 nach DIN zulässigen Hauptlegierungskomponenten gegenüber den nach DIN für Al 99,5 zulässigen Restlegierungskomponenten ist gewährleistet, daß die erfindungsgemäße Aluminiumlegierung ein deutlich homogeneres Gefüge aufweist, wodurch die Festigkeit und die Streckziehbarkeit verbessert ist und gleichzeitig die Neigung zur Grobkornbildung reduziert ist. Gleichzeitig bleibt die Dehnbarkeit zumindest auf gleichem Niveau. According to the previously derived and The stated problem is solved in that the sum of the Alloy proportions of at most two Main alloy components the sum of the Alloy proportions of the remaining alloy components exceeds at least a factor of 5. Through the Overweight according to the invention of at most two for Al 99.5 main alloy components permitted according to DIN compared to the permissible according to DIN for Al 99.5 Remaining alloy components ensures that the aluminum alloy according to the invention clearly has a more homogeneous structure, resulting in strength and the stretchability is improved and at the same time the Tendency to coarse grain formation is reduced. At the same time the elasticity remains at least at the same level.
Gemäß einer ersten Ausgestaltung der erfindungsgemäßen Aluminium-Legierung wird eine Verdoppelung der Streckgrenze bei gleichzeitiger Erhöhung der Festigkeit um bis zu 50% dadurch gewährleistet, daß die Summe der Legierungsanteile der Hautplegierungskomponenten die Summe der Legierungsanteile der Restlegierungskomponenten um mindestens den Faktor 10 übersteigt.According to a first embodiment of the invention Aluminum alloy will double the Yield point while increasing strength guaranteed by up to 50% that the sum of the Alloy proportions of the skin care components Sum of the alloy proportions of the remaining alloy components by at least a factor of 10.
Eine Aluminiumlegierung mit besonders hoher Streckgrenze und guter Festigkeit bei gegenüber Al 99,5 gleichbleibender Dehnung ist dadurch gewährleistet, daß Eisen und Mangan die Hautplegierungskomponenten bilden.An aluminum alloy with a particularly high yield strength and good strength compared to Al 99.5 constant stretching is ensured by the fact that Iron and manganese form the skin care components.
Eine Optimierung der Streckgrenze und der Festigkeit ist bei einer erfindungsgemäßen Aluminiumlegierung dadurch gewährleistet, daß der Legierungsanteil von Mangan zwischen 0,35% und 0,45% liegt.An optimization of the yield strength and the strength is in an aluminum alloy according to the invention ensures that the alloy content of manganese is between 0.35% and 0.45%.
Eine erfindungsgemäße Aluminiumlegierung bei der Eisen die einzige Hauptlegierungskomponente bildet, weist eine gegenüber Al 99,5 verbesserte Streckgrenze und Festigkeit bei gleichzeitig verbesserter Dehnbarkeit auf.An aluminum alloy according to the invention in iron the only main alloy component is one improved yield strength and strength compared to Al 99.5 with improved stretchability.
Die Eigenschaften einer erfindungsgemäßen Aluminiumlegierung werden sowohl für den Fall, daß Eisen und Mangan die Hauptlegierungskomponenten bilden als auch für den Fall, daß Eisen die einzige Hauptlegierungskomponente bildet, dadurch gewährleistet, daß der Legierungsanteil von Eisen zwischen 1,25% und 1,35% liegt.The properties of an inventive Aluminum alloy are used both in the event that iron and manganese form the main alloy components as well in the event that iron is the only one Main alloy component forms, thereby ensuring that the alloy content of iron between 1.25% and 1.35%.
Um die für Wärmeabschirmbleche vorteilhaften physikalischen Eigenschaften des Aluminiums möglichst umfangreich zu nutzen, ist es vorteilhaft, daß bei einer erfindungsgemäßen Aluminiumlegierung der Legierungsanteil von Aluminium mindestens 98% beträgt.To the advantageous for heat shields physical properties of aluminum as possible extensive use, it is advantageous that at a aluminum alloy according to the invention the alloy portion of aluminum is at least 98%.
Dadurch, daß der Legierungsanteil von Silizium 0,2% nicht übersteigt, ist gewährleistet, daß die erwünschte Erhöhung der Streckgrenze und der Festigkeit bei zumindest gleichbleibender Dehnbarkeit und reduzierter Grobkornbildung erreicht wird. Aus denselben Gründen ist es vorteilhaft, wenn der Legierungsanteil von Magnesium 0,003% und/oder der Legierungsanteil von Zink 0,03 nicht übersteigt.Because the alloy content of silicon is not 0.2% exceeds, it is ensured that the desired Increase in the yield strength and strength at least constant extensibility and reduced Coarse grain formation is achieved. Is for the same reasons it is advantageous if the alloy content of magnesium 0.003% and / or the alloy content of zinc 0.03 not exceeds.

Zur Gewährleistung der erwünschten Eigenschaften der erfindungsgemäßen Aluminiumlegierung ist es jedoch vorteilhaft, wenn der Legierungsanteil von Titan 0,03% und/oder der Legierungsanteil von Chrom 0,02% nicht übersteigt.The also permissible according to DIN for Al 99.5 Alloy proportions of chrome and titanium affect the desired properties of the invention Aluminum alloy also above that according to DIN given alloy proportions initially.
