متن کاملRAPID COMMUNICATION Nanocomposite (Nd,Dy)(Fe,Co,Nb,B)5.5/α-Fe multilayer magnets with high performance
The structural and magnetic properties of rare-earth nanocomposite magnets of a (Nd,Dy)(Fe,Co,Nb,B)5.5 single layer and a (Nd,Dy)(Fe,Co,Nb,B)5.5/α-Fe multilayer prepared by sputtering and heat treatment have been investigated. Incomplete exchange coupling behaviour is observed in the Ti-buffered NdDyFeCoNbB + 40 wt%Fe single layer magnet. After annealing, the laminated nanostructure consisting ...
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 کاملEffect of P addition on nanocrystallization and high temperature magnetic properties of low B and Nb containing FeCo nanocomposites
The P content dependencies of the nanocrystallization behaviors and high temperature magnetic properties of the Fe 54.6 Co 29.4 Si 2.8 (B 0.8ÀY P Y) 14 Nb 1 Cu 1 (Y ¼ 0, 0.2, and 0.3) alloys have been investigated. Alloys were prepared by melt spinning and subsequently annealed in an argon atmosphere to induce nanocrystallization. P addition increases primary crystallization temperature (Tx 1),...
متن کاملNear equiatomic FeCo alloys: constitution, mechanical and magnetic properties
Alloys based on the near-equiatomic FeCo offer exceptional magnetic properties. The equiatomic alloy was ‘invented’ in 1929, it offers a saturation hardly lower than that of the maximum obtained for Fe-0.35Co, with higher permeability and a lower coercivity than the latter. However, this alloy remained without industrial application, mainly because of its extreme brittleness. Only with the addi...
