Cooling zones - microstructures with light metal alloys for cast parts produced

摘要

There are a method for the casting of light metal components with high strength and high extensibility is provided. The casting can be a moulding. A molten light metal alloy, in a hollow space of a casting mold. The molten light metal alloy is bonded, and subsequently, a solid component is removed from the casting mold. The solid component is designed in such a way that the a thin wall. For example, the solid component, at least one dimension of less than or equal to about 2 mm. In this way, a cooling zones - microstructure is formed, which extends over the at least one dimension of the solid light metal alloy component extends. The solid component can therefore essentially free of a formation of a dendritic microstructure, which hold more even of alloying materials become possible than previously possible during the casting were. Such methods can be used for metal alloy - vehicle components with high strength, high extensibility and to form a small weight.
