摘要: Abstract Precipitation and growth behavior of mushroom-like Ni 3 Al phase along the dual (γ + γ′) eutectic γ − γ′ area interfaces as-cast JG4246A Al-based alloy were investigated by using short time cyclic heat treatment. Results showed that vacancies, small angle grain boundaries dislocations formed during treatment, which promoted precipitation this location. In addition, concentration gradient elements between areas more rapid pipe diffusion provided contributed to directional phase.
