Abstract	The evolution of grain boundary phases during high temperature creep has been systematically investigated in a directionally solidified Ni-base superalloy. At the primary creep stage, precipitation of nanosize M5BB3 boride from γ matrix and phase transformation from M23(C,B)6 borocarbide to M5B3B boride occur at grain boundaries. At the steady-state creep stage, precipitation of blocky M23(C,B)6 borocarbide and coarsening of M23(C,B)6 with the dissolution of M5BB3 boride occur at grain boundaries. At the tertiary creep stage, precipitation of M5B3B boride from γ matrix or phase transformation from M23(C,B)6 borocarbide to M5BB3 boride occur again at grain boundaries. The precipitation of M5B3B is due to diffusion of B atoms promoted by applied tensile stress during high temperature creep, and the phase transformation between M23(C,B)6 and M5BB3 is thought to correlate strongly with the strain rate of different creep stages.
