A transmission and scanning electron microscope study has been conducted on the deformation and fracture behavior of Rene 95, an advanced superalloy developed for use as a disk material in gas turbine engines. In addition to the normal solid solution strengthening and precipitation strengthening mechanisms, Rene 95 derives part of its strength from thermomechanical processing. In this paper, the tensile mechanical properties, deformation structure and tensile fracture characteristics of Rene 95 are examined and related to the microstructure. The results are compared with those from the conventionally processed material without TMP, and an attempt is made to account for the factors that influence the tensile characteristics of these two materials.
