The morphology of deformation induced dislocations in polycrystalline Ni₃(Al, Cr) containing M_(23)C_6 precipitates has been investigated in terms of transmission electron microscopy(TEM). Fine Polyhedral precipitates of M_(23)C_6 appeared in the matrix by aging at temperatures around 973 K after solution annealing at 1423 K. TEM examination revealed that the M_(23)C_6 phase and the matrix lattices have a cube-cube orientation relationship and keep partial atomic matching at the {111} interface. After deformation at temperature below 973 K, typical Orowan loops were observed surrounding the M_(23)C_6 particles. At higher deformation temperatures, the Orowan loops disappeared and the morphology of dislocations at the particle-matrix interfaces suggested the existence of attractive interaction between dislocations and particles. The change of the interaction modes between dislocation and particles with increasing deformation temperature can be considered as a result of strain relaxation at the interface between matrix and particles.
