Abstract：

Influence of RE on transformation cure of undercooling austenite and microstructurve after forging in test steels is studied. The result shows that the RE of solid solution RE in steels have the alloying action and that the RE make CCT curve of undercooling austenite move towards right and affect the microstructure after forging.
