Both, the bending strength and fracture toughness are determined by applying force parallel or perpendicular to the easy axis of the sintered Nd–Fe–B magnet produced using traditional power metallurgy routes. The anisotropy of mechanical properties in sintered Nd–Fe–B magnets has been observed. The XRD and SEM analyses show that the grain of ingots prefers to grow perpendicular to easy axis of Nd 2Fe 14B and induces the formation of flake-like layer of matrix phase and RE-rich phase. This distribution may be retained during magnetic field alignment, and compact. It ultimately leads to difference in the binding energy between grains parallel and perpendicular to the easy axis and induces the anisotropy of bending strength and fracture toughness.
