Magnetic properties and structure of Nd-Fe-B melt-spun alloys for isotropic bonded magnets

Magnetic properties and structure of Nd-Fe-B melt-spun alloys for isotropic bonded magnets

The phase evolution and magnetic properties of both melt-spun NdₓFe₉₈.₉₋ₓB₁.₁ x = 10-39 mass % ribbons and isotropic bonded magnets have been investigated. A high coercivity and remanence has been shown to be attainable even in the as-spun state with Nd in the range of x = 28-30 mass % without heat...
