| 2 | Magnetic Properties of Nd_8Fe_(83)Co_3B_6 Nanocomposite Magnets显示文摘The influence of quenching technology, annealing temperature and time on the structures and magnetic properties of Nd8Fe83Co3B6 nanocomposite magnets was investigated. The results show that the α-Fe/Nd2 Fe14 Bnanocomposite magnet containing a small amount of B is difficult to form amorphous state. The magnetic properties of 26 m/s quenched Nd8Fe83Co3B6 powders annealed at 640℃×480 s reach iHc=513 kA/m, Br=1.05 T and (BH)max=92.0 kJ/m3. The grain size is Da-fe=21.5 um and DNd2Fe14B=30.2um. | Fazeng LIAN, Guiqin ZHOU, Wenli PEI and Xueqin YAN (School of Materials and Metallurgy, Northeastern University, Shenyang 110006, China) | 2000 | Journal of Materials Science & Technology2000，16，2： | 1 |
| 3 | Influence of Alloy Elements on Magnetic Properties of Fe-based Amorphous Alloys显示文摘The influence of alloy elements on dc and ac magnetic properties of Fe79M2Si6B11C2(M is V, Mo or Cr) amorphous alloys was investigated. The variation law of the magnetic properties and the loss with the different elements was studied. The results show that the addition of V, Cr or Mo elements reduces the saturation magnetic induction in varying degrees. The addition of V element increases the permeability, decreases the coercivity and drops the loss. The addition of Cr and Mo reduces the permeability, and increases the coercivity. | Guiqin ZHOU, Fazeng LIAN and Guozhen LI (Institute of Materials and Metallurgy, Northeastern University, Shenyang 110006, China) | 2000 | Journal of Materials Science & Technology2000，16，2： | 1 |
| 4 | Temperature stability and microstructure of ultra-high intrinsic coercivity Nd-Fe-B magnets显示文摘The variations of intrinsic coercivity and remanence of sintered Nd-Fe-B magnets with ultra-high intrinsic coercivity were investigated. The results showed that the intrinsic coercivity and remanence declined simultaneously with increasing temperature, but the squareness of the magnets has hardly been changed. The temperature coefficients of remanence (α) and coercivity (β) for the magnets were calculated by two different methods, and the variations of the temperature coefficients and the microstructure of sintered Nd-Fe-B magnets were analyzed. The temperature coefficients of remanence (α) and coercivity (β) for the sintered magnets are very small, and the existence of fine microstructure is necessary to obtain sintered Nd-Fe-B magnets with ultra-high intrinsic coercivity. | HU Zhihua CHENG Xinghua ZHU Minggang LI Wei LIAN Fazeng | 2008 | Rare Metals2008，27，4： | 1 |
| 5 | Study on Compound Effect of Bonded Magnets显示文摘The compound effect of Nd2Fe14B/Fe3B-Ferrite bonded magnets was studied.The result shows that the value ofβjHC obviously decreases with the ferrite content increasing.In addition, a functional relation between magnetic properties and ferrite content was clearly revealed by the physical relation in the magnetic powders. | Chang Ying Ma Nuo Yu xiaojun Li Wei Liu Changsheng Lian Fazeng | 2004 | Journal of Rare Earths2004，22，z1： | 1 |
| 6 | Effect of the Partial Substitution of V for Nb on the Magnetic Properties of Fe-based Nanocrystalline Alloy显示文摘The variation of the magnetic properties of the nanocrystalline alloys for the partial substitution of V for Nb with crystallizing treatment temperature and time was investigated. The variation law of the magnetic properties with the annealing temperature and time is essentially the same. The magnetic properties of the Fe-based nanocrystalline alloys for the partial substitution of V for Nb reduce, and the crystallizing treatment temperature of the alloys increases. The optimum properties of Fe74Cu1Nb3Si13B9 nanocrystalline alloys crystallized at 550℃x60 min are uo=9.2x104, um=54.8x104, He=1.14 A/m and Bs=1.26 T. The best properties for Fe74Cu1Nb2.5V0.5Si13B9 alloys annealed at 560℃x60 min are uo=8.79x104, um=50.18x 104, Hc=1.26 A/m and Bs=1.24 T. | Guiqin ZHOU, Fazeng LIAN and Guozhen LI (Institute of Materials and Metallurgy, Northeastern University, Shenyang 110006,China) | 2000 | Journal of Materials Science & Technology2000，16，6： | 0 |

The effect of the variation of x and y on magnetic properties and thermal stability of the alloys were studied. The magnetic properties for the Pr0.85La0.15Co4.3 and Pr0.75La0.25Co4.1 magnets are iHc=368 kA/m, Br=0.91 T, (BH)max=145.6 kJ/m3, αBr=-0.03%/℃ and iHc=568 kA/m,Br=0.8 T, (BH)max=127.2 kJ/m3,αBr,=-0.06%/℃, respectively The phase structures of as-cast alloys and magnets were | Fazeng LIAN (Dept. of Materials Science and Engineering, Northeastern University, Shenyang, 110006, China)Meiqing HUANG, S.Simizu and W.E.Wallace (Carnegie Mellon Institute, Carnegie Mellon University, Pittsburgh, PA 15213, USA) | 1995 | Journal of Materials Science & Technology1995，11，6： | 0 |
