Abstract

Monocrystalline specimens of the y'-hardened nickel-base superalloy SRR 99 were examined by X-ray line profile measurements in the undeformed as well as in different high-temperature creep-deformed states. Deformation-induced residual long-range internal stresses were determined for the phases y and y’ respectively, in all <100>-directions.
