| Abstract Scope |
Additive manufacturing has emerged as a promising technology to produce complex and customized components. In this study, laser directed energy deposition (L-DED) was employed for additive manufacturing of AlNiCo magnets from elemental powders. Laser power and scan speed were varied systematically to evaluate the influence of these parameters on the microstructure attributes (grain morphology and crystallographic texture). Post L-DED, the samples were subjected to annealing treatments at 840oC at various times to examine the extent of spinodal decomposition forming B2 (magnetic) and L12 (non-magnetic) phases. Concurrently, observations were made on the changes occurring in the microstructure due to heat treatment. Magnetic properties such as coercivity and remanence were recorded. Finally, the annealed samples were subjected to tempering treatments for further enhancing the magnetic properties via redistribution of constituent elements into B2 and L12 phases. The current study provided a pathway to additively produce AlNiCo permanent magnets from elemental powders. |
