Abstract
The effect of amorphous powder blend on the magnetic and mechanical properties of die-upset Nd–Fe–B magnets has been investigated. The results showed that the intrinsic coercivity and rectangularity of demagnetization curves declined with increasing amorphous powder content. The Vickers hardness of die-upset Nd–Fe–B magnets first declined, and then increased with increasing amorphous powder content. The maximum Vickers hardness and fracture toughness of die-upset Nd–Fe–B magnets were obtained at the amorphous powder content of 10wt%, but the excessive amorphous powder made the crystallographic alignment and magnetic properties of die-upset Nd–Fe–B magnets decline sharply. The microstructure shows that the addition of amorphous powder can inhibit the grain growth of die-upset Nd–Fe–B magnets.
