Combination of room temperature He ion implantation and swift heavy ion (SHI) irradiation in the multiple ion track overlapping regime has been used to study helium porosity in EP450 ODS steel containing crystalline or fully amorphous Y-Ti nano-oxides. It was found that helium bubbles formed during post-irradiation annealing have much better adhesion to amorphized precipitates in comparison with crystalline ones. However, this does not affect the overall porosity of the alloy which is defined by helium bubbles formed on structural defects inside the ferrite grain body and on grain boundaries. © 2019 Elsevier B.V.
