Web1 de jan. de 2024 · Applications of Nd–Fe–B magnets have rapidly expanded since the mid-1980s. However, because of the low Curie temperature of Nd 2 Fe 14 B compound (312 °C) and relatively low intrinsic coercivity, high-end Nd–Fe–B magnets can be used only around room temperature. Heavy rare earth, such as Dy and Tb, modification enhances the … Web17 de nov. de 2009 · Permanent magnet properties of sintered Nd‐Fe‐B between −40 and +200 °C D. Li, H. Mildrum, K. Strnat Materials Science 1985 Easy and hard‐axis magnetization curves, and second quadrant demagnetization lines were measured on two early commercial Nd‐Fe‐B based pilot products at temperatures between −40 and +200 …
