It is shown that at the gases absence, the phase of released martensite (sorbitol) swells much later than the ferrite phase. It was found that the addition of 2 appm He/dpa leads to the fact that sorbitol loses its resistance to pore formation, and at 160 appm He/dpa sorbitol swells in the same way as ferrite. At Helium concentrations less than 500 appm there is a rapid increase in swelling, and above 500 appm growth slows down. In the stationary stage, Helium reduces the swelling of all steels that have been studied by reducing the pore size. Hydrogen, as well as He, accelerates the onset of swelling during the incubation period. Triple irradiation with Cr + He + H, compared with irradiation with only heavy Cr ions, shortens the incubation period of swelling, but to a lesser extent than double irradiation with Cr + He or Cr + H.
