“…A non-destructive testing technique called dye penetrant testing is used to find surface flaws in castings. It entails the application of a penetrating liquid to the casting's surface, typically a colored dye (45). Any surface flaws are penetrated by the dye, which is then dragged out with the help of a developer to produce a visual indication the flaw.…”

The casting process is a crucial manufacturing method utilized in numerous sectors to create intricate components and forms. However, there are a number of underlying causes of casting flaws that can result in subpar quality, higher costs, and decreased productivity. This review seeks to give a general overview of casting process flaws, their causes, and possible fixes. The evaluation will go over the various possible flaws, including porosity, shrinkage, and surface abnormalities, as well as their underlying causes, which include design, material, and process characteristics. Furthermore, the review will focus on various remedial measures that can be taken to overcome these defects and improve casting quality, such as changes in design, material selection, and process optimization. This review will be useful for researchers and practitioners in the casting industry who are interested in improving their understanding of casting defects and developing effective remedial measures to enhance product quality and efficiency.

The twin-roll casting (TRC) of light metal alloys, in particular aluminium and magnesium alloys, represents a promising technology for the production of lightweight components thanks to its short process chain and promising combinations of properties. In the production of strip products, TRC is susceptible to a number of defects due to the coupled process steps of casting and forming, which prevent its use for more complex alloy combinations in the field. In this review, the defects in TRC of light metal alloys will be summarized and discussed. In addition to a basic classification of the defect types and definition of these, the formation mechanisms and avoidance strategies will be discussed. Special focus is placed on centreline segregation defects and surface bleeds, which occur in a large number of investigations in the literature. Effective avoidance strategies are defect-specific, but are mostly due to the combination of the plant design of the TRC process, the TRC parameters or the use of alloying elements to influence the solidification process.

A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and a roll load greater than 2 kN/mm. A vertical-type high-speed twin-roll caster can cast aluminum alloy strips at a speed higher than 10 m/min and a roll load smaller than 550 N/mm due to the effect of the large thermal conductivity of copper alloy rolls, compared with that of steel rolls. However, the properties of an aluminum alloy strip cast at a roll load smaller than 140 N/mm and at a roll speed higher than 30 m/min are not clear. In this study, Al–5%Mg strips were cast at a roll speed of 30 m/min and roll loads of 2 and 88 N/mm using a vertical-type high-speed twin-roll caster. The effects of roll load on cracking at the strip surface, the tensile mechanical properties, and the microstructure were investigated. Rotating rolls were stopped during casting, and the progression of centerline segregation and the microstructure between the rolls was investigated. Centerline segregation and surface cracking were lower at 2 N/mm than at 88 N/mm. In the strip cast at 2 N/mm, elongation in the width direction was greater than that cast at 88 N/mm, due to decreased surface cracking. The results demonstrate that a very low roll load improves the properties of the cast strip.
