Formatted Abstract/Summary
A range of surface defects commonly formed on vertical direct chill (VDC) cast products have been examined by various metallographic techniques. Whilst the presently accepted model for the formation of cold folds on the cast surface can be reconciled to the details observed in these examined samples, the suggested explanations for the formation of other common surface defects could not. This paper describes current research efforts aimed at measuring the strength of the molten aluminium alloy oxide skin under various conditions. This data is used as the basis for understanding the behaviour of the melt surface in the meniscus region of a VDC mould during casting. The results obtained from the surface skin strength tests and the metallographic examination of the cast samples are discussed and a framework of possible factors responsible for the formation of various surface defects is proposed.
