Study on Preparation of Sintered NdFeB with TbDyFe Alloy AITranslate
Abstract AITranslate
TbDyFe alloy or DyFe alloy plus terbium metal were used as the raw materials to prepare high performance sintered NdFeB with the similar smelting equipment and process.Comparison was made of thickness distribution,chemical composition,microstructure and magnet properties between the two strip casting products prepared with the same ingredient proportion but in different addition ways.And magnetic properties were investigated of sintered NdFeB magnets with lower terbium content.NdFeB alloy composition was designed according to RE（Pr,Nd,Tb,Dy）_（32.6）M（Fe,Co,Al,Ga,Cu,Nb,Zr）_（bal）B_（1.0）（mass fraction）.The results show that different material addition ways have no obvious effects on the appearance,thickness distribution and microstructure of strip casting products.However,effective terbium components increase by 10.71% in the strip casting product with TbDyFe alloy as the raw material,its magnet coercivity increases by 14.04%,and the remanence slightly decreases.Using TbDyFe alloy with 10% lower terbium dosage of DyFe alloy plus terbium metal,the prepared sintered NdFeB can reach the magnetic property level of the latter,greatly saving the rare earth resources.
