Modification of sintered iron properties by Y2O3 nanoparticles
Department of Physics of Metals, Faculty of Physics, T.Shevchenko National University of Kyiv, 4 Glushkova Ave., 03680 Kyiv, Ukraine
Influence of Y2O3 nanoparticles on sintered iron structure and microhardness is investigated. Ferrite grain growth is shown to be slowed down by the clusters which cause altering the grain shape from needle-like to equiaxial (with lower specific surface). Yttrium oxide particles resulted microhardness increasing to 3.6 GPa at 1 % of second phase content. The fact is explained by retardation of dislocations on disperse particles by the Orowan mechanism.
