Abstract

Abstract: Sintered rare-earth NdFeB is an important functional material, which is broadly applied in automobile, medical equipment and aerospace fields etc. The preparation, application and control of physical stability were reviewed through involving in optimizing the composition and tailoring grain boundary structure, exploring the effects on micro mechanism of the stability through powder metallurgy route. The influence of chemical composition and microstructure on the stability of the magnetic fields and temperature was concluded by analysing the stability of sintered Nd-Fe-B magnets under different conditions.

Key words: rare-earth, sintered NdFeB, physical stability, rising routes
