摘要：
Differential thermal analyses along with microstructural characterization has been used to study the solidification path in the Ni-based superalloy CMSX 10 K. It was found that solidification initiates with freezing of primary gamma dendrites, continues with a peritectic reaction resulting in nucleation and growth of gamma' particles in the interdendritic liquid, and terminates with the precipitation of fine lamellar [gamma-gamma'] phases between the coarsened gamma' particles.
