Ultrastrong nanocrystalline oxide-dispersion-strengthened ferritic alloy with exceptional thermal stability

As structural materials candidates of advanced fission and future fusion reactors, oxide-dispersion-strengthened (ODS) alloys, which are often ultrafine-grained (with a grain size between 100 and 1000 nm), have attracted widespread interest in past decades. However, fabrication of fully dense bulk nanocrystalline ODS alloys has rarely been reported. In this work, a novel Zr-doped nanocrystalline 14YWTZ ferritic ODS alloy...
