| Abstract Scope |
In this study, we investigated the phase transformation, microstructure, and mechanical properties of nanocrystalline FeAlV alloys synthesized by an out-of-equilibrium aerodynamic method—namely, high-energy mechanical alloying (mechanosynthesis). Elemental powders of iron, aluminum, and vanadium were processed using a planetary ball mill (RETSCH PM 400) to obtain the FeAlV alloy system under non-equilibrium conditions. Inspired by prior work on Fe-based systems, we focused on understanding the influence of vanadium content and milling duration on alloy formation and structural evolution.
Phase identification and microstructural analysis were primarily conducted using Mössbauer spectroscopy, which revealed the presence of disordered Fe-rich solid solutions and magnetic environments, confirming the formation of Fe–M (M = Al, V) alloyed phases. Complementary characterizations, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and Vickers microhardness measurements, further demonstrated the effects of milling parameters on crystallite size reduction, lattice strain, and mechanical strengthening. |
