Abstract The increasing demand for Nd-Fe-B magnets has resulted in a large backlog of rare-earth Ce metals indirectly.
In order to improve the utilization rate of rare-earth Ce and reduce the production cost of Nd-Fe-B magnets,
（Nd, Ce）-Fe-B magnets could be prepared by dual-main phase alloy method, which provided an effective way to
solve the above problem. By exploring the composition of high Ce-contained strip casting and preparation process,
Ce-Fe-B and（Nd, Ce）-Fe-B strip casting with good dendrites structure and almost no α-Fe phase have been successfully
prepared. Among the prepared sintered magnets, the remanence of（Nd, Ce）-Fe-B magnets reaches to
11.33 kGs and that of Ce-Fe-B magnets reaches to 8.037 kGs, which provide data guidance for the later preparation
of high performance and high Ce-contained dual-main phase sintered magnets.
