Nanoscale hybrid magnets containing SmCo5 and Nd2Fe14B hard magnetic phases have been produced via a novel ‘‘in-one-pot’’ processing route. The grain size of the processed bulk composite materials is controlled below 20 nm. The refinement of the nanoscale morphology leads to effective inter-phase exchange coupling that results in single-phase like magnetic properties. Energy product of 14 MGOe ...

Neodymium iron boron magnets (NdFeB) play a critical role in various technological applications due to their outstanding magnetic properties, such as high maximum energy product, remanence and coercivity. Production of NdFeB is expected rise significantly the coming years, for this reason, demand rare earth elements (REE) will not only remain but it also increase even more. The recovery has bec...

Abstract Sintered neodymium-iron-boron (NdFeB) magnets and lithium-ion (Li-ion) batteries are essential in a number of clean energy technologies such as electric vehicles wind turbines. The United States (US) has some manufacturing capacity for Li-ion almost no producing sintered NdFeB magnets. As result, the US imports significant quantities these Trade statistics on imported magnets, however,...

Abstract Sintered NdFeB materials are more and widely used in the military field because of their excellent magnetic performance cost performance. The demagnetization caused by impact was discussed this paper to provide a theoretical basis for application NdFeB. Firstly, experimental platform material under built, corresponding load calibrated using thin-film piezoelectric sensor. In experiment...

Abstract The incorporation of strong magnetic powders (NdFeB) into cement mixtures has produced improved mechanical properties pastes. (cementitious magnet) used a simple and inexpensive process to form complex forms the NdFeB magnet. Particulate been distributed uniformly in matrix. composites increased density compressive strength with concentration. Magnetization (stable up one year) also po...
