Deformation and texture formation mechanism of hot-deformed SmCo5 nanocrystalline magnets

Realizing the deformation and texture formation mechanism of the HD SmCo5 magnets were rarely re-ported, which restricted the further enhancement of its magnetic properties. Here, we prepared the ani-sotropic SmCo5 nanocrystalline magnets by hot pressing and hot deformation (HP-HD). The magnetic properties, texture, and microstructure of the magnets with different height reductions were systematically studied. Based on the characterization results, for the HD SmCo5 nanocrystalline magnets, it is inferred that the deformation and texture formation mechanism are attributed to the coordination of precipitated phases, dislocation slip, stacking fault formation, and regular grain rearrangement.(c) 2022 Published by Elsevier B.V.
