Abstract: The uniform of the heat treatment process and NdFeB alloy powder metallurgy technology on the α-Fe soft phase effects. Experimental results show that the uniform of the heat treatment process can significantly reduce the α-Fe soft phase of the content, and the thinning, also found that the remaining α-Fe soft phase sintering and after annealing and hard to deal with after the occurrence of magnetic exchange coupling And its magnetic properties can have a greater impact, so this experiment for the Development of the fourth generation of rare earth permanent magnets laid the foundation.
