| Abstract: | Recent progress on the third generation permanent magnet—high performance sintered NdFeB magnets,especially,the design of composition and the production process,was previewed in this article.The effect of some elements,such as Dy,Tb,Al,Cu,Co,Zr,Nb and Ga,on the magnetic properties and the advanced production process,such as Hitachi Low Oxygen Process（HILOP）,Strip Casting(SC), Jet Milling(JM)，Rubber Isostatic Pressing(RIP)and binary alloys process,had been introduced in detail.On these bases,the principle to design the alloy composition and the reasonable production process were introduced. |
