Abstract
- Lab‐scale additive manufacturing of (CoCuFeZr)17Sm2‐based powder is carried out to realize CoSm‐printed parts with hard magnetic properties. For manufacturing a special inert gas, process chamber for laser powder bed fusion is used. A three‐step annealing procedure analogous to sintered magnets is applied. This leads to a coercivity of 2.77 T, remanence of 0.78 T, and maximum energy density of 109.4 kJ m−3 for the printed parts. Compared with an isotropic sintered magnet of comparable composition and annealing procedure, the coercivity is of the same order. Due to the texture of the printed parts, the remanence is 24 % larger. [ABSTRACT FROM AUTHOR]
