| Abstract: | Effects of alloying additions of Co and Zr on microstructure and magnetic anisotropy of the HDDR powder of Nd Fe B alloy were investigated. It was found that the HDDR powder of Nd Fe Zr B alloy is nearly magnetically isotropic, but that of Nd Fe Co Zr B alloy is remarkably anisotropic. A new Zr rich phase is formed in the homogenized Nd Fe Zr B alloy and keeps undecomposing during the HDDR process. The co addition of Co drastically depresses the formation of the Zr rich phase and results in higher Zr content of the hard magnetic phase than in the Co free alloy. The results suggested that a sufficient solubility of alloying elements such as Zr into the hard magnetic phase via the optimization of chemical composition of Nd Fe B alloy is the key for the production of anisotropic Nd Fe B alloy powder by the HDDR process. |
