ODS EUROFER Steel Strengthened by Y-(Ce, Hf, La,nSc, and Zr) Complex Oxides

Original language description

Oxide dispersion-strengthened (ODS) materials contain homogeneous dispersions ofntemperature-stable nano-oxides serving as obstacles for dislocations and further pinning of grainnboundaries. The strategy for dispersion strengthening based on complex oxides (Y-Hf, -Zr, -Ce, -La)nwas developed in order to refine oxide dispersion to enhance the dispersion strengthening e ect.nIn this work, the strengthening of EUROFER steel by complex oxides based on Y and elements ofnthe IIIB group (lanthanum, scandium) and IVB group (cerium, hafnium, zirconium) was explored.nInterparticle spacing as a dispersoid characteristic appeared to be an important factor in controlling thendispersion strengthening contribution to the yield strength of ODS EUROFER steels. The dispersoidnsize and average grain size of ODS EUROFER steel were altered in the ranges of 5–13 nm andn0.6–1.7 m, respectively. Using this strategy, the yield strength of the prepared alloys varied betweenn550 MPa and 950 MPa depending on the doping element
