| 摘 要： | 在(Nd,Fe)(76.5)Co_(15)Al_1B_(7.5)的基础上,研究丁Nd,Fe量变化对合金性能的影响,其形式为Nd_(18-x)Fe_(58.5+x)Co_(15)Al_1B_(7.5),x=1,2,3,4,结果合金最佳性能出现在Nd量为15—16at％之间。同时研究了用W,Mo,Zr,Nb替代Al的工作,其替代式为Nd_(16)Fe_(76.5)Co_(15)B_(7.5),M_1,M为W,Mo,Zr,Nb。W替代Al的合金有较好的磁性能和热稳定性能。

| Abstract: | The magnetic properties of Nd-Fe-Co-Al-B alloys were studied, taking alloy Coi5Al1B7.5 as a basis, with the aim of clarifying the influences of Nd and Fe contents, Experimental composition of the alloy system is defined as Nd18-x. Fe58.5+xCo15Al1B1.5 with x=1,2,3 or 4. It is shown that an optimum property will be obtained if the Nd conten is chosen from 15 to 16 at%.The study on using M = W, Mo, Zr, or Nd as a substitute for Al in a substitution form of Nd16 Fe76.5Co15B7.5M, has been carried out. The results show that W is better than others for better magnetic properties and thermal stability. |
