(Pr,Nd)-Fe-B nanocrystalline magnetic materials with TiC additions
The effect of titanium carbide (TiC) addition and Pr substitution in nanocrystalline Nd-Fe-B based magnetic materials has been investigated. Rapidly solidified (Pr,Nd)-Fe-B alloys were prepared by melt spinning. The compositions studied were ( Pr x Nd 1 − x ) 9.5 Fe 84.5 B 6 ( x = 0 , 0.1, 0.25, 0.5...
