Abstract
Recently, the ODS ferritic steels are very much noticed as nuclear fusion structural materials and long life fuel claddings of fast breeder reactors. It was investigated on the ion irradiation damage of ferritic 12%Cr ODS steels with the addition of Ti and W in comparison with 17%Cr ODS and 12%Cr-3W ODS steels that cavitied were formed during simultaneous irradiation of 3.2MeV Fe^+ ion and 330KeV He^+ ion at 973K. It was found in the 12%Cr ODS steels with addition of Ti and W that cavity formation was restrained by ultrafine oxide and increase in dislocation density. But it was also found in the 17%Cr ODS and 12%Cr-3W ODS steels that large cavity was formed due to coarse oxide and decreased density of dislocations.
