Yi-min, HE Hao, ZENG Zhao-yi (State Key Laboratory for Powder Metallurgy, Central South University, Changsha 410083, China) Abstract: Fe-50%Ni soft magnetic alloy was prepared through metal injection molding (MIM) technique using carbonyl iron powder and carbonyl nickel powder as raw materials. The effects of microstructure and impurity levels on the magnetic properties of MIM Fe-50%Ni soft......
Preparation and drug releasing property of magnetic chitosan-5-fluorouracil nano-particles WANG Dong-sheng(王东生)1, LI Jian-guo(李建国)2, LI He-ping(李和平)3, TANG Fa-qing(唐发清)4 1. Institute... releasing process. In contrast to 5-Fu, the release speed of 5-fluorouracil from magnetic chitosan-5-fluorouracil nano-particle is much slower. The slower releasing property may be not only due......
STUDY OF MECHANISM OF RQ EMBRITTLEMENT OF Fe73.5Cu1- Nb3Si13.5B9 NANOCRYSTALLINE SOFT MAGNETIC ALLOY W.Z.Chen1,Y.G.Wang2,S.X.Zhou1,E.Sukedai3,X.G.Cao4,J.L.Huang4 (1.National Engineering Technology... Nb3Si13.5B9nanocrystalline soft magnetic alloy (FINEMET) during production process. As a re-sult of RQE the ductility of the as-quenched ribbon drops seriously. The mechanism ofRQE has been elucidated in the recent works......
-current magnetic property testing equipment. The results indicate that when the sample is annealed at 300 ℃ for 1 h, the grain size of Ni-Fe alloy foils is still about 10 nm and the Ni-Fe alloy foils have... alloy foil; direct-current magnetic property 电沉积Ni-Fe合金箔是一种纳米晶软磁合金.纳米晶软磁合......
