Abstract：The ribbon samples of Fe-base amorphous alloys Fe_(80)B_(20)(A),Fe_(77.84)B_(16.81)Si_(3.49)C_(1.86)(B),Fe_(65.66)Co_(17.3)B_(15.84)Si_(1.2)(C)and Fe_(65.92)Co_(17)B_(13.29)Si_(1.59)C_(1.1)P_(1.1)(D)wereprepared by melt spinning.Their saturation magnetization at 12 KOe was deter-mined by extracting sample magnetometer and magnetic balance in the tempera-ture range of 1.5—300 K or 300—1200K respectively.It was obtained that themean magnetic moment per atom of transition metal,μ,is(2.03—2.07)μ_R forall samples.Both alloys A and B have similar room temperature saturation mag-netization,σ_S(R.T.),and Curie temperature,T_C,but alloys C and D are higherabout 6% and 10% than those of A respectively.As the experimental results ofthe thermomagnetization,resistivity,DSC and X-ray diffraction,the crystallinephases were also analyzed.The crystallization temperature,T_(cr),of alloys C andD is similar to that of alloy A,and T_(cr)of alloy B is higher about 80 K thanthat of A.The effect of chemical bond,T_(cr)vs e/a and the complexity crystal-line phases on the stability of the Fe-base amorphous alloys has been discussed. 收稿日期: 1985-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 陈金昌 司红 沈保根 詹文山 赵见高 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I3/115 1 Hasegawa,R.;O' Handley,R.C.;Mendelsohn,L.I.,AIP Conf.Proc.,34(1976) ,298． 2 Fukamichi,K.;Kikuchi,M.;Arakawa,S.;Masumoto,T.,Solid State Commun.,23(1977) ,955． 3 Hasegawa,R.;Ray,R.,J.Appl.Phys.,49(1978) ,4174． 4 Luborsky,F.E.;Becker,J.J.;Walter,J.L.;Liebermann,H.H.;IEEE Trans.Magn.,MAG-15(1979) ,1146． 5 沈保根;郭慧群;章志英;詹文山,待发表. 6 Hatta,S.;Egami,T.,J.Appl.Phys.,50(1979) ,1589． 7 Luborsky,F.E.;Walter,J.L.,IEEE Trans.Magn.,MAG-16(1980) 572． 8 Roy,R.;Majumdar,A.K.,J.Magn.Magn.Mater.,25(1981) ,83． 9 Liebermann,H.H.;Graham,C.D.,IEEE Trans.Magn.,MAG-12(1976) ,921． 10 Kissinger,H.E.,Anal.Chem.,29(1957) ,1703． 11 Mizoguchi,T.;Yamauchi,K.;Miyajima,H.,“Amorphous Magnetism”Proc.of Int.Symp.on Amorphous Magnetism,17-18,Aug.1972,Detroit,Michigan,Eds.Hooper,H.O.;DeGraaf,A.M.,Plenum Press,New York-London,1973,p.325． 12 詹文山;沈保根;郭慧群;章志英;潘孝硕,第五届全国磁学会议报告,会议文集,I,1983,p.95． 13 Mangin,Ph.;Marchal,G.,J.Appl.Phys.,49(1978) ,1709． 14 Chien,C.L.;Hasegawa,R.,Amorphous Magnetism II,Eds.Levy,R.A.;Hasegawa,R.,Plenum Press New York,1977,p.287． 15 Handrich,K.,Phys.State Solid,32(1969) ,K55． 16 Naka,M.;Tomizawa,S.;Masumoto,T.;Watanabe,T.,Proc.2nd Int.Conf.on Rapidly Quenched Metals,MIT Press,1976,p.273． 17 陈金昌;沈保根,待发表.
