Abstract
The speaker will discuss research in which a mechanically alloyed austenitic stainless steel (MA304LZ) was characterized as a candidate accident-tolerant fuel cladding material. The chemical composition of MA304LZ is similar to that of 304L SS with a 0.7% wt addition of high-purity Zr for refining grain size and forming Zr-oxide precipitates to enhance mechanical properties, corrosion resistance, and irradiation tolerance. MA304LZ was found to have improved mechanical properties and corrosion resistance compared with those of 304L SS; however, void swelling remains an issue.
