Popis: ~irconium alloys used in the production of tubes for reactor channels are subjected to creep while in service at ~ 300-350~ This article presents the results of a study of crack kinetics under creep conditions in a 2r-2.5% Nb. An analysis of data on crack growth under creep conditions shows that such cracks may be described by a stress intensity factor K, as in linear-elastic fracture mechanics, and crack growth can be described by the equation [i]
