Microstructure and tensile properties of ODS ferritic steels mechanically alloyed with Fe2Y

Microstructure and tensile properties of ODS ferritic steels mechanically alloyed with Fe2Y

An oxide dispersion strengthened ODS ferritic steel has been produced by mechanical alloying of Fe–14Cr–2W–0.2Ti (wt.%) prealloyed powder with 0.55 (wt.%) Fe2Y intermetallic particles and consolidated by hot isostatic pressing. The microstructure after thermal treatments confirms the homogeneous pre...
