Abstract

The assumption that the Q_c in the chemical-mechanical correlation model is the creep activation energy was verified. Verification was carried out by deriving values of Q_c from stress corrosion cracking (SCC) for various materials and comparing these values with creep activation energies (Q_creep) obtained from creep tests and reported in the literature. Materials investigated included austenitic stainless steels (SS), nickel alloys, copper alloys, aluminum alloy, and silver chloride polycrystalline. Results showed a match between Q_c and Q_creep for the materials investigated.
