The performance of neodymium magnet
Unique dual-alloy process is developed and applied. The liquid phase of well-controlled auxiliary alloy composition can infiltratethe 2:14:1 phase grain sufficiently. Uniform rare-earth-rich phase is made around 2:14:1 grain by auxiliary alloy liquid phase, so as to increase value of Hcj. In the meantime, rare earth in auxiliary alloy liquid is stopped outside the principal phase by controlling sintering time and temperature, so that epitaxial layer of principal phase gets high anisotropy, and so to stop Js of principal phase to decrease. Magnet for Direct Drive Wind Generator has to be of very high comprehensive performance to stand harsh working environment and very long life time
