Alloy Castings

Entrapped double oxide films are known to be the most detrimental defects in cast aluminium alloys. The research reported here was aimed at surveying the results of previous researches studying how these defects develop with time, with the intention of understanding their behaviour in the liquid metal once they have formed. This would give a better understanding of factors influencing the properties of light metal alloy castings which will lead to the development of improved practices by which healthier castings with reliable and more reproducible properties are obtained.

To assess the effect of the mould filling modes on the content of oxide films in castings, special criterion is proposed that provides prediction in the contamination of chill castings mаde of aluminum alloys by using modern computing tools to simulate the moulds casting process on computer. It is noted that decrease in the value of the contamination criterion by using alloys with low content of Mg or without this component reduces the possibility of controlling the distribution of oxides in the casting, other elements of the casting mould and using the concentration of oxides, for example, in washers to control the mechanical properties of cast products. This is due to increase in the duration of oxidation processes in gas-tight mould with such change in the composition of the casting material.
