Special features of the diffusional growth and dissolution of pores in pearlitic heat-resistant steel 12Kh1MF

A special feature of the diffusional growth of pores in creep of steel 12Kh1MF is the cumulation of chromium atoms on the pore surface. This effect may have a substantial influence on the kinetics of the growth and on the dissolution of pores because chromium slows down the diffusion of vacancies.
