Abstract :
[en] The influence of the densification step, performed by uniaxial pressing at room temperature, on the coercivity of NdFeB bonded magnets has been analyzed. The mass density does not play any role on of non-cured magnets prepared by the mentioned method. Due to the brittle and intergranular character of the Nd Fe B-based phase fracture, the nano-sized grains are not affected or the modification is negligible, which maintains unchanged. After curing, the intrinsic coercivity of themagnets is reduced as a function of the compaction pressure increase.
