| Abstract: | A study of creep fracture for a steam turbine rotor material is presented in this paper. Creep damage, crack initiation and fracture toughness at the material working temperature have been determined. The crack growth increment is measured by a DC potential method. The correlations between the crack growth rate and various fracture parameters have been analysed. |
