Abstract (en)
[origin: WO9106107A1] A two-phase permanent magnet which has not only excellent magnetic characteristics but also significantly high corrosion resistance. It is manufactured by use of two magnetically useful phases as the starting materials. One is an RE2TM14B phase having a high residual flux density; the other is a low-melting RE-TM phase and/or RE-TM-B phase which contributes to the improvement of sinterability and has a function of cleaning the main phase grain boundary and a property of causing the resultant material to be an electrochemically noble composition.
