Abstract

Abstract: Microstructure and mechanical properties of carbide dispersion strengthened (CDS) steels
fabricated by mechanical alloying are investigated. After 60 hours' ball milling, the solid solution process of main
alloy elements was completed. At the same time, the added carbide particles significantly improve the tensile
mechanical properties. The strength and hardness of the materials are obviously higher than that of CLF-1 steel.
The elongation and fracture morphology of CDS steels also indicate a fairly good result of ductility.

Key words: ODS steel, Carbide dispersion strengthening, Mechanical alloying
