Abstract
It has been found that initiation of pores in welded joints of heat-resistant pearlitic steels and their initial evolution under conditions of low-temperature service creep is mostly of a diffusion character, while their further development is of a dislocation character.
Keywords: thermostable steels, welded joints, pore initiation, carbides, creep, failure, service life
