| Abstract: | Evolution of Ni3Al phase in a nickel-base directionally solidified superalloy has been investigated during creep rupture testing (1253 K/150 MPa). Besides the splitting, rafting and Ostwald ripening cases, many finer Ni3Al particles have been firstly observed to precipitate from the rafted Ni3Al particles. A simple qualitative interpretation has been proposed. |
