Modeling solidification and mushy zone deformation of alloys

The deformation of the partially solidified strand during near net shape continuous casting of thin slabs is only one example of a technologically important process where a mushy zone is mechanically altered in order to achieve improved grain structures and homogeneity. However, the phenomena occurring during plastic deformation of a solidifying mush are poorly understood, have not been observed directly, and have not been modeled in detail. A mathematical model that predicts the temperature and solid fraction profiles, liquid concentration evolution, and solid phase displacement during the de...
