1Densification and properties of ODS-iron based alloy显示文摘Y_2O_3 dispersion strengthened iron-based powders and oxide dispersion strengthened(ODS) alloys were prepared by hydrothermal synthesis and spark plasma sintering(SPS),respectively.The effects of Y_2O_3,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 show that the best mechanical properties are obtained with 1 wt.% Y_2O_3 addition.The size of agglomerated particles can 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.Guo, Zhimeng Liu, Qing Yang, Weiwei Guo, Leichen 2012Rare Metals2012,31,4:2
