| 摘 要： | The influence of Zr addition on the microstructure and magnetic properties of nanocomposite Nd10.5Fe78-x Co5ZrxB6.5(x=0-5)alloys was investigated. It was found that the intrinsic coercivity could be significantly improved by the addition of 2% (atom fraction) Zr. The presence of small amount of amorphous phase is responsible for tile low intrinsic coercivity for Zr-free alloy. The small amount addition of Zr may suppress the growth of grains of α-Fe and Nd2Fe14B phases. The more homogeneous microstrueture with an average grain size of 20 nm can be obtained for Nd10.5 Fe76 Co5Zr2B6.5 alloy.
