Self-propagating Combustion Synthesis and Characterization of ODS Fe-base Superalloy Powders

摘要：

　　A new method was employed to synthesize nano-sized Y2O3 dispersion strengthened Fe-base superalloy powders using self-propagating combustion.A concentrated solution of nitrates of iron and yttrium was used as oxidizer,malic acid as fuel to fabricate Fe2O3/Y2O3 powders at low temperature.Afterwards,uniform and fine Fe/2wt.%Y2O3 powders were obtained by selective reduction with hydrogen,on the surface of which dispersive Y2O3 particles of the mean size of 30 - 50 nm were observed.
