| titleOfInvention | A kind of didymium holmium yttrium multielement rare earth alloy permanent magnetic material and preparation method |
| abstract | A kind of didymium holmium 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 , Re is Nd, Pr, and Re ' is Ho, 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≤32,6≤β+η≤13,2≤η≤8,1.01≤δ≤1.09,0≤ζ≤0.23,0.35≤ε≤0.68, γ=100-alpha-beta-η-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, adding of Ho, Y is conducive to reducing the outfield needed for alloy saturation magnetization, reduce the use amount of Nd, Pr simultaneously, and adopt general electrolytic stove to produce, thus reduce the production cost of enterprise, in addition, the appearance affecting permanent magnetic material performance α – Fe can also effectively be avoided. |
