Microstructure and Mechanism of Coercivity Enhancement of Sintered Nd-Fe-B Magnet by Grain Boundary Diffusion

Ningbo Yunsheng Co., Ltd.

Rare earth element (REE) based Nd-Fe-B magnets have been widely used because of their excellent magnetic properties. The applications of Nd-Fe-B rare earth permanent magnets include hybrid electric vehicles (HEVs), power generators for wind turbines, high performance industrial motors, hard disk drives (HDD) for computers, traveling wave tubes for satellite communications, headphones and speakers, washing machines, and other consumer electronic devices. Furthermore, as well known, Dy and Tb are used as an additive to Nd-Fe-B magnets to increase the coercivity (because they increase the magneto-crystalline anisotropy) of magnets. But the magnetic moment of Dy and Tb are coupled anti-parallel to that of Fe, which decrease the magnetization and maximum energy product of the magnet. <read more>

StanMagnetics Bootcamps: Basic and Advanced
August 8th
Denver, Colo.


MAGNETICS Magazine is pleased to announce workshops beyond those held in conjunction of our annual conference. Join us August 8th in Denver for a one-day Magentics Bootcamp, presented by Dr. Stan Trout. The Magnetics Bootcamps focus on teaching the basics of Magnetics with an emphasis on permanent magnets. If you need to understand magnets better for your job or are new to the field, the Basic Bootcamp I is the perfect place to start. Assumes that one has little or no background in magnetics. The Bootcamp I workshop will cover the essential fundamental magnetic concepts such as hysteresis, the nature of magnetism, units, basic magnet processing, magnetizing and thermal effects. If something more advanced is what you are looking for, attend Advanced Bootcamp II. Assumes someone has either taken a previous Bootcamp, (Bootcamp I), or has some technical understanding of magnetics. After a brief review of the basics, covered topics include self-demagnetization and loadlines, rare earth raw materials and their pricing, advanced processing techniques, manufacturability, design basics, case studies and what’s new on the horizon.
