چکیده انگلیسی
Relationships between the alignment magnetic field Halign of NdFeB powders and the thermal stability of their sintered magnets were investigated on the base of observing the domain structure and microstructure. The thermal stability increased before 0.6â¯T and then decreased with the enhancement of Halign. The action of Halign is manifested in rotating magnetic particles and higher Halign increases the alignment degree of matrix phase and optimizes the magnet microstructure, thus increasing the magnetic ordering and minimizing the magnetostatic energy of aligned particles. Better magnetic ordering and lower magnetostatic energy are sensitive to the temperature, accounting for the reduction of thermal properties after 0.6â¯T.
