Rare-earth permanent magnetic materials have been widely used in the fields of communication£¬transportation£¬medical and aerospace£¬owing to their extraordinarily high remanence£¬high coercivity and high magnetic energy product.The development of reasonable£¬self-consistent and reliable thermodynamic database of rare-earth permanent magnetic materials and the investigation of microstructure evolution during a variety of manufacturing process have both significantly theoretical and practical values to alloy design and process optimization.In this work£¬the related phase equilibria relationships and applications of part of rare-earth magnetic materials were investigated using CALPHAD method This work mainly focuses on:

1.Nd-B and Cr-Nd binary systems£¬Fe-Nd-B and Fe-Cr-B ternary systems were thermodynamically reassessed with the aim of obtaining more reasonable thermodynamic parameters and more accurate phase relations.B-Nd-Cr and Fe-Nd-Cr ternary systems were optimized.Based on the metastable experimental information£¬the reasonable£¬self-consistent and comprehensive thermodynamic description of Fe-Nd-B-Cr quaternary system considering metastable phases Fe3B£¬Fe23Nd2B3 and Fel7Nd2B was developed.
2.Based on the obtained thermodynamic database and CALPHAD technique£¬alloy design and microstructure evolution conceming Fe-Nd-B magnetic materials were investigated.Solidification behavior under different cooling rate:isothermal phase transformations and phase precipitate sequence at various melt undercoolings were analyzed and predieted using step rule and largest driving force crietia respectively according to the different situations.
3.Co-Ho binary system was thermodynamically optimized.The calculated results can reproduce well the corresponding experimental data A set of self-consistent thermodynamic parameters describing various phases in this binary system has been obtained.
