INFLUENCE OF HEATING RATE ON MICROSTRUCTURE AND MAGNETIC PROPERTIES OF Fe3B/Nd2Fe14B NANOCOMPOSITE MAGNETS
The nanocomposite magnet, which is composed of exchange coupled nanocrystalline soft (Fe3B, α-Fe) and hard (Nd2Fe14B) magnetic phases, was first reported by Coehoorn et al. [1], and the theoretical basis of it was reported by Kneller and Hawig [2]. Nd-Fe-B based nanocomposite magnet has attracted considerable research interest due to its excellent magnetic properties with relatively low amount ...
متن کاملEffect of selective Co addition on magnetic properties of Nd2(FeCo)14B/-Fe nanocomposite magnets
Nd2Fe14B/α-Fe-based hard/soft nanocomposite magnets with Co addition have been prepared by ball-milling and warm compaction. It was found that Co addition into the magnetically hard phase improves magnetic properties significantly, especially the remanence ratio and coercivity. The effect on the magnetic properties of the selective Co addition may be attributed to enhanced interdiffusion across...
متن کاملQuantum Mechanical Simulation of Nanocomposite Magnets on CRAY XT3
One of the grand challenges in the development of nanotechnology is how to synthesize and process “designed nano-structured” materials. An important example of these materials is the nanocomposite permanent magnets made of hard and soft phased magnetic nanoparticles located on a superlattice. Binary phase magnets, if they can be devised, could double the energy product of current single-phase m...
متن کاملThe Effect of Heat Treatment on Microstructure and Magnetic Properties of Nd17Fe76.5B5Cu1.5 Type Sintered Magnets
The effects of high temperature homogenization and low temperature annealing treatments on the microstructure and magnetic properties of sintered magnets of an Nd17Fe76.5B5Cu1.5 type alloy have been investigated. The microstructure of the as-cast alloy, consisted of three phases including a Nd2Fe14B1 (2:14:1- type) matrix phase Cu-containing Nd-rich Phase and Free α-iron. The as-sintered magnet...
