We demonstrate that high-energy ball milling of gas-atomized maraging steel powder followed by suitable thermal-treatment produces nanocrystalline maraging steel powders having improved magnetic properties, compared to the gas-atomized powders. Milli

We investigated the influence on the structural and magnetic properties of gas-atomized maraging steel powder during mechanical milling. The as-received powder comprised, primarily, martensite phase (α) and traces of retained austenite (γ); the sat

Nanocrystalline Fe46Co34Ni20 alloy powder was successfully fabricated by mechanical alloying. The alloy powder (mean particle size ~ 5.4 μm and grain size ~ 15 nm) was composed of two phases—the f.c.c. phase and the b.c.c. phase. At 300 K, the sat

We evaluated the suitability of Fe40Co30Ni30 as a precursor for Fe-rich FeCoNi-based high-entropy semi-hard magnets. Mechanically alloying the metal powders 40 at.% Fe, 30 at.% Co, and 30 at.% Ni for 12 h effected micron-size Fe40Co30Ni30 powder comp
