기계적으로 합금화 시킨 Fe-12-17%Cr 페라이트계 산화물 분산강화 (ODS) 합금의 이온조사에 의한 공공의 형성에 미치는 Ti 및 W 첨가의 영향 = Research Papers/Mechanical Behaviors:Effects of Ti and W Addition on the Cavity Formation by Ion Irradiation in Fe-12-17%Cr Base MA-Oxide Dispersion Strengthened (ODS) Ferritic Alloys

다국어 초록 (Multilingual 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.
