摘要： An oxide dispersed strengthened (ODS) metal alloy comprising oxide particles dispersed in a metal alloy matrix, wherein the metal alloy matrix comprises an intragranular cellular microstructure, and wherein the oxide particles are dispersed in at least some of the cells of the intragranular cellular microstructure; or a method of additively manufacturing a metal alloy with oxide particles. The metal alloy and oxide may be mixed by a ball mill and the oxide particles may be deposited on the surface. Slowing the scanning speed increases the cell size (fig 5). The ODS metal alloy may be stainless steel. The metal alloy matrix may have a structure of a melt pool (fig 4a and 4b) comprising a plurality of grains each comprising the intragranular structure. The oxide particles may be present in between at least some of the boundaries between adjacent grains as well as within at least some of the cells of the structure. The oxide particles may be metal oxides, preferably Yttrium Y2O3 nanoparticles of 1-200 nm. The design is preferably for heat exchanges resistant to neutron damage and high temperatures for nuclear fusion reactors.
