| 摘 要： | 述了两类合金元素(代换元素：Co，Dy或Tb与掺杂元素：M1(低熔点元素)：Cu，Al，Ga，Sn，Ge，Zn等与M2(高熔点元素)：Nb，Mo，W，Zr，Ti，V，Cr等)的添加对烧结Nd-Fe-B永磁合金的显微结构和磁性能的影响。综述了两种合金化方式(传统合金化方式：在熔炼前加入合金元素；晶间合金化方式：在球磨或气流磨前加入合金元素)对烧结Nd-Fe-B磁体显微结构和磁性能的不同影响；最后指出晶间合金化复合添加方式是一种很有前景的生产高性能Nd-Fe-B磁体的方法。

| Abstract: | The effects of two kinds of elements (substituent:Co, Dy or Tb and dopant elements:M1(low-melt ing elements):Cu,Al,Ga,Sn,Ge,Zn an d M2(high-melting elements):Nb,Mo, W,Zr,Ti,V,Cr)on microstructure and magnetic properties of sintered Nd -Fe-B permanent magnets are briefl y reviwed. The different effects of two kinds of adding methods(conven tional alloying technique:alloying elements added before melting and intergranular alloying technique:a lloying elements added before ball -milling or jet-milling)on sintere d Nd-Fe-B magnets are summarizedF inally,it is concluded that interg ranular alloying technique of blen ding additives is a kind of promi sing method to produce high performance Nd-Fe-B ma gnets |
