Abstract Scope Nanocrystalline maraging steel powders were fabricated by mechanical milling. The structure of the milled powders was characterized by x-ray diffraction, scanning electron microscopy, and transmission electron microscopy, followed by the characterization of their magnetic properties at sub-ambient (~60 K), ambient, and elevated temperatures (~900 K). The particle size and grain size of the powder particles were less than ~5 μm and ~15 nm, respectively. The pristine alloy powder, at ambient temperature, was primarily comprised of martensite. The intrinsic coercivity (HC) and saturation magnetization (MS) was estimated as ~5 kA/m and ~165 Am2/kg, respectively. While, both HC and MS increased at sub-ambient temperatures, they both decreased at elevated temperatures. Thermal treatment of the powder resulted in an increase in MS and a decrease in HCI. The magnetic properties of the nanocrystalline alloy were compared with their bulk counterparts and with similar nanocrystalline semi-hard as well as soft-magnetic alloys.
