Comprehensive study on the sintering behavior of yttria nano-powder in contact with electrolytic iron using the rapid solidification processing technique

Oxide dispersion strengthened (ODS) steels are considered as the future structural material of interest for nuclear power plants, due to their elevated creep resistance at higher operation temperatures. In this study, a 0.3wt% nano-yttria (Y2O3) dispersed iron cast trial was elaborated using rapid solidification processing (RSP). The nano-sized Y2O3 particles were introduced into the iron matrix using the formulation of a low-concentrated colloidal dispersion.
