Firstly, the reaction thermodynamics was analyzed. Then, the reaction mechanism was studied, and the results are as following:① Ca moves to the surface of Dy〓O〓 by vapor phase;② Dy〓O〓 reduced to Dy by Ca is fast;③ Dy moves to the Fe surface mainly by vapor and various Dy-Fe alloys are produced gradually;④ The forming process of DyFe〓 may be described by Contracting Core Model;⑤ The rate-controlling step of the reaction is the Dy diffusing toward contracted and nonreaction nuclear center Fe.
