Abstract:The relationship between the main technological parameters(magnetic induction and cooling rate) and the non-dendritic structure of aluminum alloy produced by electromagnetic stirring was studied. The evolution of the non-dendritic structure was semi-quantitative described, and the semi-quantitative relationship between the magnetic induction and cooling rate and the non-dendritic structure parameters was obtained, which offer the theoretic direction to choose the technological parameters for producing the aluminum alloy with non-dendritic structure.

 

Key words: semi-solid forming; aluminum alloy; non-dendritic structure; electromagnetic stirring
