| titleOfInvention | A kind of didymium dysprosium yttrium multielement rare earth alloy permanent magnetic material and preparation method |
| abstract | A kind of didymium dysprosium yttrium multielement rare earth alloy permanent magnetic material, consists of Ren α re 'n β re "n η bn δ cun ζ aln ε fen γ , it is characterized in that, Re is Nd, Pr, and Re ' is Dy, Re, and " for Y, Fe are Fe and inevitable impurity, α, β, η, δ, ζ, ε, γ are each constituent mass degree; Wherein, 30≤alpha+beta+η≤32,5≤β+η≤12,3≤η≤7,1.02≤δ≤1.09,0≤ζ≤0.24,0.33≤ε≤0.67, γ=100-alpha-beta-δ-ζ-ε.The problem of the alloy pig generation segregation that the present invention efficiently solves the different and manual operation factor of the fusing point of each component in traditional fusion process and to cause after melting, Dy adds the actual coercive force being conducive to improving alloy pig, and the alternative part Nd of the interpolation of Y, Pr, and then reduce the production cost of enterprise, in addition, the appearance affecting permanent magnetic material performance α – Fe can also effectively be avoided; Thus improve the performance of alloy pig material. |
