| Abstract Scope |
Oxide dispersion-strengthened (ODS) steels, with their exceptional mechanical properties at high temperatures and increased resistance to neutron irradiation embrittlement, hold great promise for future use in nuclear and fusion power systems. Our research aims to unlock their full potential by exploring the use of ultrasonically gas-atomized precursor steel powder with oxide nanoparticles or steel powder with smart surface oxidation, in combination with laser powder bed fusion (LPBF) techniques, to enhance ODS steel performance in extreme high-temperature conditions. We planned to start with austenitic 316L stainless steel and incorporate Y2O3 nanoparticles for their superior ultimate tensile strength. Later, we introduced TiB2 nanoparticles to further enhance strengthening mechanisms associated with nano oxide dispersion. |
