摘要：

The working principle and peculiarities of new electromagnetic rheocasters, which are based on the use of rotating permanent magnets and which allow the production of intense stirring in solidifying semisolid alloy slurries, are described. Local measurement techniques are applied to the study of the evolution of the electromagnetic, hydrodynamic, and thermal phenomena with time inside vigorously agitated melt-solid mixtures. Satisfactory performances concerning the microstructure of solidified aluminum thixotropic slurries (homogeneity, crystal shape, grain size, and fraction of primary solid) were obtained.
