A study was conducted on the stability of the nanostructure of the sintered material. The effect of adding carbon on the structure and the crystallite size was studied for the sintered material. The X-ray diffraction technique was used to identify the new phases and measure the crystallite size as well as the microstrains induced by mechanical alloying. Scanning electron microscopy revealed structural changes in the milled and sintered material.enMechanical alloyingNanostructureFe-Cr alloysNanocrystalliteSinteringArticle
