Machine Learning-Based Prediction and Interpretation of Hot-Tearing Susceptibility in Al–Zn–Mg Alloys for Direct-Chill Casting Process Optimization
Hot tearing limits the yield of Al–Zn–Mg billets produced by direct-chill casting. Its governing factors span composition, cooling conditions and the state of the partially solidified metal, and they interact; several quantities required by physics-based criteria cannot be measured during casting, and the factors are s...
