The influence of remelting on the properties of AlSi6Cu4 alloy modified by antimony

Medlen D., Bolibruchova D.

Archives of Foundry Engineering

2012

Vol. 12, iss. 1

81-86

The paper deals with the problem of multiple remelting influence on AlSi6Cu4 alloy modified by antimony on chosen mechanical characteristics, microstructure and gas content. This foundry alloy is used mostly in automotive industry. Foundry Aluminum-Silicon alloys are also used in number of industrial weight sensitive applications because of their low weight and very good castability and good mechanical properties. Modifiers are usually added to molten aluminum-silicon alloys to refine the eutectic phase particle shape and improve the mechanical properties of the final cast products and Al-Si alloys cast properties.

Influence of antimony on the mechanical properties and gas content of alloy AlSi6Cu4

73-78

Aluminium alloys based on Al-Si are used in automotive and aerospace industries. AlSi6Cu4 alloy is used the complicated castings, which must comply high strength requirements. Strength characteristics can also be affected by the modifiers: Na, Sr, Sb. In the literature is mentioned, that AlSi6Cu4 modified by sodium and strontium has negative effect - increases of the gas absorption. Modification of AlSi6Cu4 alloy by antimony, is still not mentioned in the literature. The article gives the effect of antimony on selected mechanical properties and gas content of foundry alloy AlSi6Cu4.

Investigation results of gas hold-up in the air-lift reactor with inner or reversed circulation are presented in the paper. Gas was supplied to the air-lift reactor system by the ring sparger. Measurements were conducted for coalescing and non-coalescing gas-liquid systems. The results were elaborated mathematically (Eq.(1))).
