AbstractThe dependence of the creep rupture strength on the microstructure of a liquid metal cooling directionally solidified nickel based superalloy was investigated over a wide range from 980 to 1100 degrees C. The creep rupture lives were prolonged especially at 980 degrees C/310 MPa as a result of the elimination of the blocky primary gamma '. The fractured specimens were sectioned and examined to reveal the deformation microstructures and active dislocation deformation mechanisms.
