Magnetic and Microstructural Characteristics of a DyF$_{3}$ Dip-Coated Nd-Fe-B Sintered Magnet

Autor: Kyoung-Hoon Bae, Taesuk Jang, Seong Rae Lee, Seok Namkung, Tae-Hoon Kim

Publikováno v: IEEE Transactions on Magnetics. 49:3251-3254

We investigated the microstructural and magnetic property changes of DyF3 dip-coated Nd-Fe-B sintered magnets as a function of the first post-sintering annealing (PSA) temperature and clarified the optimum first PSA temperature for the dip-coating pr

Effect of Cu and DyF3Powder Additions on the Coercivity of Sintered Nd-Fe-B Magnets

Autor: T.H. Lim, Dhani Ram Dhakal, Taesuk Jang, Seok Namkung, M.W. Lee, Tae-Hoon Kim, Seong Rae Lee

Publikováno v: Journal of Korean Powder Metallurgy Institute. 19:247-252

Effect of Cu and powder mixing with Cu-free (Nd, Dy)-Fe-B jet-milled powder on the magnetic properties of sintered magnets was investigated. The coercivity of a magnet prepared from the Cu-free (Nd, Dy)-Fe-B powder was about 10 kOe even though the al

Variation of Magnetic Properties of (Nd, Dy)-Fe-B Sintered Magnets with Compaction Conditions

Autor: Taesuk Jang, Seok Namkung, M.W. Lee, S.J. Han

Publikováno v: Journal of Korean Powder Metallurgy Institute. 19:1-5

In order to improve the remanence of (Nd, Dy)-Fe-B sintered magnets, we investigated the influence of compaction conditions such as packing density, applied field and green density on the magnetic properties. While the remanence decreased with increa

A Study on the Fabrication of 2700 Series Al-alloy Sintered for Automobile Application

Autor: Taesuk Jang, Tae-Whan Lim

Publikováno v: Journal of the Korea Academia-Industrial cooperation Society. 12:5438-5442

In order to use as weight-reduced sintered parts for automobiles, mechanical properties of sintered compacts of 2712 Al-alloys containing 0, 10, 20, and 33% ceramics, respectively, were investigated in this study. (1)Regardless of ceramic contents, a

Magnetic and Microstructural Characteristics of Nd-Fe-B Sintered Magnets Doped With Dy$_2$O$_3$ and DyF$_3$ Powders

Autor: Seong Rae Lee, Tae-Hoon Kim, Song-E Park, Donghwan Kim, Taesuk Jang, Seok Namkung

Publikováno v: IEEE Transactions on Magnetics. 47:3259-3262

Magnetic and microstructural properties of (Nd26.06, Dy6.51)-Febal.-B0.97-M2.39 (wt.%) ( M = Cu, Al, Co, and Nb) sintered magnets doped with Dy2O3 and DyF3 powders were studied. In the case of the Dy2O3-doped magnet, Dy was distributed along the near

Enhanced Oxidation Resistance of Iron Nanoparticles via Surface Modification in Chemical Vapor Condensation Process

Autor: Taesuk Jang, Dongwon Lee, Byoung-Kee Kim, Ji-Hun Yu

Publikováno v: Journal of Materials Science & Technology. 26:367-370

In order to prevent the oxide formation on the surface of nano-size iron particles and thereby to improve the oxidation resistance in ordinary condition, iron nanoparticles synthesized by a chemical vapor condensation method were directly soaked in h
