Steel toughness has been greatly improved in the last two decades by adopting innovative technologies such as advanced steelmaking, grain refinement and thermo‐mechanical treatment. The technology of oxide metallurgy is not a simple part of either chemical metallurgy or physical metallurgy. It aims at the generation of finely dispersed oxides by chemical metallurgy and using these oxides together with the methods of physical metallurgy such as IGF (intragranular ferrite) technology and phase transformation. Oxide metallurgy can be an effective way in addition to the conventional austenite grain refinement to obtain higher toughness for structural steels.
