Abstract (en)
[origin: WO2017076801A1] The invention relates to a method for producing a light metal cast component from a melt comprising an aluminium casting alloy which contains, respectively by weight, 3.5 to 5.0% silicon, 0.2 to 0.7% magnesium, 0.07 to 0.12% titanium, at most 0.12 % boron, optionally less than a total of 1.5% of other alloy elements, the remainder being aluminium and unavoidable impurities. The melt is produced from a basic melt, a first grain refiner comprising an aluminium-silicon alloy and a second grain refiner comprising an aluminium titanium alloy wherein, relative to the total weight, the melt contains in total an amount of 0.1 to 5.0% of the first and second grain refiners; wherein the casting is carried out by the low-pressure method and, after casting, the melt is subjected to pressure.
