摘要
The microstructure of a rapidly solidified single crystal Ni-base superalloy treated by laserglazing has been observed by TEM and STEM-EDAX techniques.Various morphologies of extraordinary flower-like MC carbide of TiC type were revealed in the nar- row interdendritic regions.While the superfine γ′ precipitate and higher density of dislocation were found in the γ matrix.
