Optimizing processing parameters for semi-solid casting: a comprehensive review

Semi-solid processing has gained popularity in the casting industry due to its significant advantages, offering a net shape single or multistep flexible process. This study aims to establish an evaluation criterion to understand the relationship between processability and its impact on outcomes. Pouring temperature and fluidity emerge as primary factors, while solidification and viscosity demonstrate secondary importance in the processing. Through a multi-angle evaluatory approach, the flexibility of all semi-solid casting process parameters can be assessed based on alloying elements, temperature gradient, fluidity, heat transfer, and solidification.
