Abstract

The research progress in aspects of the effects of chaotic advection induced by electromagnetic field on the solidified microstructure in semi-solid alloy was reviewed. The chaotic theory and its engineering application

as well as the application of the chaotic advection in the preparation of the semi-solid alloy were introduced. On this basis

the progress and the results achieved that apply the mathematical modeling to parse the chaotic advection during melt flow in semi-solid alloy were mainly expounded. Finally

the research advances on the effects of chaotic advection induced by electromagnetic field on solidified microstructure in semi-solid alloy were summarized

and the potential application and the main development direction were prospected.
