摘要: Permanent magnetic materials containing the intermetallic compound Nd2Fe14C were obtained by annealing melt‐spun flakes. As quenched flakes with compositions close to stoichiometric composition consist of α‐Fe, Nd2Fe17 some dissolved carbon, and an amorphous phase. At approximately 700 °C is formed in a solid‐state reaction. The amount formed, presence secondary phases, properties depend strongly on composition. Samples Nd13.5Fe79.6C6.9 contain only small fraction phases. remanence intrinsic coercive field are 0.72 T 800 kA/m, respectively. kinetics phase transformation, as well thermodynamics equilibria relevant part Nd‐Fe‐C system discussed.
