OPTIMIZATION OF SYNTHESIS OF ODS 9CR MARTENSITIC STEEL BY MECHANICAL ALLOYING
Keywords:
ODS – Oxide dispersion strengthening, MA – Mechanical Alloying, EDAX – Energy Dispersive Analysis of X-raysAbstract
The present study aims at the optimization of small scale synthesis and bulk production of ODS 9Cr martensitic steel alloy powders by Mechanical Alloying (MA) of elemental metal precursors. Characterization of MA powders produced in a planetary ball mill, an attritor and a double cone blender employing XRD and SEM are reported in detail. The effect of the various process parameters involved in the production of ODS alloy powders are also described. SEM images depict the various stages during the process of MA and XRD studies have confirmed the formation of solid solution.
