摘要：

The microstructural evolution of the superalloy CMSX-6 during directional solidification has been investigated in detail. The analysis of the transverse sections within the mushy region yields the solidification sequence and the solid fraction fs against the temperature decrease. Correspondingly the formed microstructure has been characterized in different zones. By means of a special treatment various theoretical models were applied to calculate the f(S)-variation for the used multicomponent system. In comparison with experimental measurement a reasonable description has been achieved.
