Abstract：The theoretical and experimental advances in regular eutectic and irregular anomalous eutectic transformation theory in recent years were reviewed. The research on the formation of regular eutectic was becoming mature and the theoretical model which can predict the experimental results was established. For the formation of irregular anomalous eutectic, a large number of experimental data had been obtained, including growth mode, growth rate, growth morphology,spatial distribution and microstructure coarsening. However, the model description and prediction were still incomplete, and the formation mechanism was still controversial. On the contrary, due to the complexity of the composition of industrial alloys, eutectic solidification theory had not been widely used. As a results, how to combine experimental and theoretical research, relax the eutectic point composition theory to the whole phase diagram, expand the solidification theory of binary alloy to the multi-alloy system, and apply the theory with the latest technical conditions to industrial production is still the direction of solidification theory research.
