Synthesis of Fe–Al Intermetallic by Mechanical Alloying Process
https://orcid.org/http://orcid.org/0000-0001-9480-3995
In the present work, mechanical alloying (MA) of iron and aluminum powder has been performed by planetary ball mills. Milling balls of different sizes 5, 15, and 20 mm in diameter were used for the milling medium. MA was done for different duration of time to refine the grain and crystallite size of the powder. Structural and phase changes occurred in the powder mixture on account of MA. The structural evolution and morphological analysis of the Fe60Al40 powder during MA were analyzed using X-ray diffraction and scanning electron microscope. MA of elemental aluminum (Al) and iron (Fe) powder results in the development of Fe(Al)-supersaturated solid solution phase. The effect of the MA on average grain size, mean crystallite size, and lattice strain was assessed. For disordered Fe(Al) solid solution milled for 40 h, these values were 10 μm, 18.2 nm, and 0.44%, respectively.
