Abstract:

Y2O3 dispersion strengthened iron-based powders and oxide dispersion strengthened (ODS) alloy were prepared by hydrothermal synthesis and spark plasma sintering (SPS) respectively. The effects of Y2O3 , vibratory milling treatment and Ti element on the microstructure and mechanical properties of the materials were investigated by Scanning Electron Microscope (SEM) and micro-electronic universal tester. The results showed that the best mechanical properties were obtained with 1 wt %Y2O3 addition. The size of agglomerated particles could be decreased to a certain degree by vibratory milling treatment. With the addition of Ti element, the tensile strength and hardness of the samples were improved
