  Mehrstofflegierung des Aluminiums, insbesondere für Kolben von Brennkraftmasehinen. 



   Es gibt Mehrstofflegierungen des Aluminiums mit über 2% Silizium, die in den Legierungsstoffen Zink, Kupfer, Silber, Zinn, Nickel, Kobalt, Molybdän, Chrom, Mangan, Titan oder Wolfram mit mindest   2%   je Komponente bei einem Aluminiummindestgehalt von   50%   begrenzt sind. Auch sind Kolbenlegierungen bekannt, die neben den Elementen Magnesium, Kupfer, Eisen, Mangan, Nickel, Kobalt, Chrom, Lithium bis zu je 2% noch Zirkon, Vanadium, Tellur, Beryllium, Strontium und Lanthan bis zu je 5% enthalten. 



   Bei diesen Mehrstofflegierungen waren die für Leichtmetallkolben wichtigen Eigenschaften, wie Wärmeausdehnung, Gleitfähigkeit, Warmfestigkeit, Härte, Abnutzung, Wärmeleitfähigkeit sowie Bearbeitbarkeit und Kokillengiessfähigkeit, in der Praxis bei der Vielfältigkeit dieser Legierungen nur in unvollkommenen Werten nebeneinander erzielbar. Z. B. ergaben hohe Prozentsätze von Silizium und Nebenkomponenten wohl einen niederen Wärmeausdehnungskoeffizienten und hohe Härte, aber auch hohe Sprödigkeit, schlechte Bearbeitbarkeit und einen unwirtschaftlichen Verschleiss. 



   Es wurde nun gefunden. dass, beiBedachtnahme auf die gegenseitige Beeinflussung der einzelnen Legierungskomponenten, innerhalb enger Legierungsintervalle mehrkomponentige Aluminiumlegierungen herstellbar sind, welche die erwähnten, für Kolbenlegierungen wichtigen mechanischen Eigenschaften nebeneinander in gleichmässig hohen Werten besitzen. Solche Legierungen, die eben den Gegenstand

  Multi-material alloy of aluminum, especially for pistons in internal combustion engines.



   There are multi-component alloys of aluminum with more than 2% silicon, which are limited in the alloy materials zinc, copper, silver, tin, nickel, cobalt, molybdenum, chromium, manganese, titanium or tungsten with at least 2% per component with a minimum aluminum content of 50% . Piston alloys are also known which, in addition to the elements magnesium, copper, iron, manganese, nickel, cobalt, chromium, lithium up to 2% each, also contain zirconium, vanadium, tellurium, beryllium, strontium and lanthanum up to 5% each.



   With these multicomponent alloys, the properties that are important for light metal pistons, such as thermal expansion, sliding ability, high temperature strength, hardness, wear, thermal conductivity as well as machinability and mold castability, could only be achieved in practice with the diversity of these alloys in incomplete values. For example, high percentages of silicon and secondary components probably resulted in a low coefficient of thermal expansion and high hardness, but also high brittleness, poor machinability and uneconomical wear.



   It has now been found. that, taking into account the mutual influence of the individual alloy components, multi-component aluminum alloys can be produced within narrow alloying intervals, which have the mentioned mechanical properties important for piston alloys side by side in consistently high values. Such alloys that are just the subject
