The "Hot-roll Nano Neo Magnet" process produces a nanograin neodymium permanent magnet encased in stainless steel in a commercially scalable process that is expected to be more cost-effective and energy efficient.

Researchers from the U.S. Department of Energy's Critical Materials Institute, led by Ames National Laboratory, have developed a "Hot-roll Nano Neo Magnet" method for manufacturing high-performance neodymium-iron-boron permanent magnets that are heat-resistant, easier, and greener to produce.

Neodymium is a rare earth metal that tarnishes rapidly when exposed to air. In 1983, it was discovere...
