Abstract
The formation of Fe-Cr alloy phase was analyzed using X_Ray Diffraction (XRD) technique to improve the synthesis process of the Oxide Dispersion Strengthened (ODS) steel. Synthesis of the ODS steel was performed using powder metallurgy method with a difference milling time of 3 hours, 5 hours and 7 hours. The phase composition and structure parameters of the Fe-Cr phase was analyzed by processing the diffraction data using the software of Rietveld refinement HighScore Plus. The crystallite size and microstrain of the alloy was calculated by the Williamson-Hall equation plot method. Results of the refinement analysis showed that the Fe-Cr alloying process has been successful for samples with milling time of 3 and 7 minutes. The milling time in the synthesis process change the crystallite size and micro-strain of the Fe-Cr alloys formed.
