Misorientation effect of grain boundary on the formation of discontinuous precipitation in second and third generation single crystal superalloys

Misorientation effect of grain boundary on the formation of discontinuous precipitation in second and third generation single crystal superalloys

[001] tilt artificial grain boundaries of Ni-based single crystal superalloys CMSX-4 and DD10 have been prepared by self-diffusion bonding. The microstructural stability of 0 ∼ 30∘ artificial grain boundaries have been investigated after heat treatment at 1100 ∘C for 0 ∼ 300 h. TCP phases and cellu...
