Abstract
Conditions under which brittle fractures occur in the elements of power equipment operating at high-temperature creep are analyzed. New local fracture criteria are proposed. An engineering method for predicting the lifetime of power equipment on the basis of a phenomenological model of brittle local fractures is developed. The use of the proposed criteria and phenomenological approach allows the lifetime of operating and newly designed power installations to be predicted with essentially better accuracy.
