Description	The service life of components designed to operate for long periods under loading at elevated temperatures is limited by the creep deformation and fracture phenomena. Possibility of a reliable prediction of the residual creep life is of major practical and economical relevance. A number of approaches has been used for the estimation of the creep damage and residual life; these approaches could be divided into two principal branches. The microscopic methods are based on the microstructural observations of accumulated damage in the samples of material after service, while macroscopic meth- ods use mechanical testing of the samples under some reference conditions. However, both approaches still do not provide enough reliable results for wide practical use, be- cause of result scatter and missing generally applicable models for the creep damage evolution. The most important factors which make the results unreliable are analyzed in the present paper. These are mainly: i) production scatter in the material' The service life of components designed to operate for long periods under loading at elevated temperatures is limited by the creep deformation and fracture phenomena.
