Definitions
- the invention relates to a method for the production of aluminum-magnesium cast alloys according to the preamble of claim 1.
- a metal melt that is ready to be cast is kept at a melt temperature of, for example, 750 ° C. for more than 50 hours.
- Aluminum-magnesium alloys with a higher magnesium content tend to be scratched after longer periods of standing.
- the presence of magnesium in the melt means that the protective oxide skin, which normally prevents oxidation of the aluminum, becomes permeable and the reaction of the aluminum with oxygen can proceed.
- a cauliflower-like scab is formed on the melt, which mainly consists of spinel (MgO ⁇ Al 2 O 3 ) Metal bath is prevented by temperature stratification.
- EP-A-0 594 509, JP-A-7 197 177 and EP-A-0 110 190 are wrought alloys with a vanadium content to achieve a recrystallization-inhibiting effect or to avoid a coarsening of the grain during homogenization is known.
- the invention has for its object by alloying Measures a higher scratch resistance for aluminum-magnesium alloys bring about as this with a beryllium additive after the State of the art is possible.
- the melt is preferred 0.02 to 0.05% by weight of vanadium added.
- magnesium With a content of more than 3.5% by weight of magnesium, an addition is sufficient from 25 to 50 ppm beryllium, preferably 25 to 35 ppm beryllium. Is the Magnesium content in the melt lower than 3.5 wt .-%, so less than 25 ppm beryllium required to provide high resistance to scratching achieve. With lower requirements for the tendency to scratch, it can even no beryllium is added.
- a preferred application of the method according to the invention lies in Manufacture of cast alloys with
- the process according to the invention for production is particularly preferred of die casting alloys.
