Improvement of thermal stability by co-introducing Dy and Co with dual-alloy method in NdFeB magnets
Journal of Materials Research and TechnologyA dual-main-phase magnet with excellent thermal stability was prepared by co-mixing two types of magnetic powders, which was the conventional N55-grade powder without Dy elements, while the Co and Dy contents reached 50 wt% and 6 wt% respectively in ...
