Abstract: Nd-Fe-B type permanent magnetic materials have been widely used in energy and rail transit due to their excellent room temperature magnetic properties. However, the continually growing demand for Nd-Fe-B magnets has greatly accelerated the depletion of critical rare earth elements including Nd, Pr, etc, which results in the rising prices of those critical rare earth elements. How to ensure the stability of the material pro-perties while reduce the excessive consumption of critical rare earth is one of the important issues that need to be solved urgently. The high-abundance rare earth Ce substitution for Nd is an effective solution. In this work, lean rare earth Ce11-xFe83+xB6 (x=0—4) alloys are prepared by melt-spinning method, and the effect of melt-spinning speed and Ce content on the phase constitution and magnetic properties of which are investigated. The results show that the increase of melt-spinning speed effectively increases the content of Ce2Fe14B hard magnetic phase during the melt-spinning process, which further improves the magnetic properties of the Ce11Fe83B6 alloy. In the melt-spinning speed range of 13—21 m/s, the Ce11Fe83B6 alloy is mainly composed of Ce2Fe17 and Ce2Fe14B phases. With the increase of melt-spinning speed, the Ce2Fe14B phase content gradually increases from 16.89% to 58.30%, and accordingly, the saturation magnetic polarization Js, remanence Jr and coercivity Hc show an increasing trend. When the melt-spinning speed is 19 m/s, the Ce11Fe83B6 alloy presents the optimum magnetic properties with the Js=0.84 T, Jr=0.41 T and Hc=106.72 kA/m. Furthermore, the Ce2Fe14B phase content gradually decreases with the decrease of Ce content. On the contrary, the α-Fe soft magnetic phase with high saturation magnetic polarization is gradually generated. When the Ce content decreases to the 7%, the increasing content of the soft magnetic phase and exchange coupling between α-Fe and Ce2Fe14B phase induce an increase of Js and Jr to 1.18 T and 0.44 T, respectively.
