Optimization of milling speed and time in mechanical alloying of ferritic ODS steel through taguchi technique

The oxide dispersion strengthened (ODS) ferritic steels are one of the most important in fuel cladding materials for 4th Generation nuclear reactors because their excellent mechanical properties such as irradiation resistance, swelling and elevated temperature tensile/compressive strength. Mechanical alloying (MA) is promising routes developing nanocrystalline ODS steel materials. For production powders, influencing factor milling speed time during process. With improper selection speed, final milled powders become an amorphous structure consisting high impurity inclusions microstructure, strength was also affected. In order to overcome these drawbacks, present investigation taken into account appropriate time, which optimized through Taguchi analysis followed by MA were characterized X-Ray Diffraction Analysis (XRD) Scanning Electron Microscope (SEM).
