Description

Aluminium-Silizium-Legierungen und Verfahren zu ihrer Herstellung Zusatz zum Patent 85& 359-Im Patent 856 359 sind Aluminium-Silizium-Legierungen mit 5 bis 20% Silizium und gegebenenfalls Zusätzen von insbesondere Mangan, Magnesium, Kupfer, Nickel usw. beschrieben, die einen Phosphorgehalt unter 0,00018 ± 0,00005% besitzen, sowie Verfahren zur Herstellung von solchen Aluminium-Silizium-Legierungen.Aluminum-silicon alloys and processes for their manufacture Addendum to patent 85 & 359-In patent 856 359 are aluminum-silicon alloys with 5 to 20% silicon and, if necessary, additions of in particular manganese, magnesium, Copper, nickel, etc., which have a phosphorus content below 0.00018 ± 0.00005% own, as well as processes for the production of such aluminum-silicon alloys.

In jüngerer Zeit haben Legierungen mit höheren Siliziumgehalten für Spezialzwecke Bedeutung erlangt, insbesondere für Werkstücke, die eine hohe Warmfestigkeit bei einem möglichst niedrigen Wärmeausdehnungskoeffizienten aufweisen. Insbesondere haben sich Legierungen mit über 20% Silizium als Kolbenlegierungen für Zweitaktdieselmotoren und andere hochbeanspruchte Verbrennungsmotoren bewährt.More recently, alloys with higher silicon contents have been used for Special purposes gained importance, especially for workpieces that have a high heat resistance have the lowest possible coefficient of thermal expansion. In particular alloys with over 20% silicon have proven themselves as piston alloys for two-stroke diesel engines and other highly stressed internal combustion engines.

Erfindungsgemäß wirkt sich auch bei Aluminium-Silizium-Legierungen, die gegebenenfalls Zusätze an Mangan, Magnesium, Kupfer und/oder Nickel in einer Gesamtmenge bis zu 10% enthalten können, die Erniedrigung des Phosphorgehaltes unter die im Patent 856 359 angegebenen Grenzen auf die Struktur der Legierung hinsichtlich der Erstarrungsform des Siliziums im gleichen Sinne aus, wenn der Siliziumgehalt auf über 20% bis auf 35%, vorzugsweise bis auf 30%, erhöht wird.. Die Änderung des Phosphorgehaltes kann nach dem bekannten und zum Teil im Patent 856 359 beschriebenen Verfahren durchgeführt werden.According to the invention, aluminum-silicon alloys also have an effect the optional additions of manganese, magnesium, copper and / or nickel in one Total amount can contain up to 10%, lowering the phosphorus content below the limits given in patent 856,359 on the structure of the alloy the solidification form of silicon in the same sense as when the silicon content is increased to over 20% up to 35%, preferably up to 30%. The change in the Phosphorus content can according to the known and partly described in patent 856,359 Procedures are carried out.
