Abstract
The behavior of interface morphology evolution of a transitional zone in CMSX-2 single crystal superalloy was investigated by using high-temperature gradient directional solidification apparatus. The results show that various solidified microstructures, such as planar, cellular and den-drite structure, and primary spacing arm of cellular and dendrite structures have been obtained with different transitional solidification processings. In addition, the accelerating model of drawing rate is favorable to successfully improve single crystal growth and microstructure integrality.
