采用单辊快淬法制备Fe_(81-x)Co_xZr_7Nb_2B_(10)(x=2,4,6)系非晶合金,并对该系非晶合金进行热处理.利用X射线衍射和振动样品磁强计研究FeCoZrNbB合金系的晶化过程和磁性能.结果表明:Fe_(81-x)Co_xZr_7Nb_2B_(10)(x=2,4,6)系合金在快淬速率为30 m/s时完全形成非晶.Fe_(79)Co_2Zr_7Nb_2B_(10)合金的晶化过程为非晶→非晶+α→Fe→α-Fe+Fe_3Zr+Fe_2Nb_(0.4)Zr_(0.6);Fe_(77)Co_4Zr_7Nb_2B_(10)与Fe_(75)Co_6Zr_7Nb_2B_(10)合金的晶化过程相同为非晶→非晶+α-Fe→α-Fe+Fe_3Zr→α-Fe+Fe_3Zr+Fe_2Nb_(0.4)Zr_(0.6).Co含量的增加抑制了退火后α-Fe晶相的形核,并促使Fe_3Zr化合物更易析出.Fe_(81-x)Co_xZr_7Nb_2B_(10)(x=2,4,6)合金的比饱和磁化强度(M_s)和矫顽力(H_c)随退火温度的变化趋势相同.530℃之前退火,随退火温度的升高M_s增加并不明显;530℃之后退火,M_s迅速上升.530℃退火,H_c达到最小值;高于530℃退火,H_c随退火温度的升高而增加.
Fe_(81-x)Co_xZr_7Nb_2B_(10)(x=2, 4, 6) amorphous alloys were prepared by single roller melt-spinning and annealed at different temperatures. The crystalline processes and magnetic properties of the alloys were studied by X-ray diffraction and vibrating sample magnetometer. The results show that whcn quenching speed reaches 30 m/s, Fe_(81-x)Co_xZr_7Nb_2B_(10)(x = 2, 4, 6) amorphous alloys are formed. The crystalline process of Fe_(79) Co_2 Zr_7 Nb_2 B_(10) is amorphous→amorphous+α- Fe→α- Fe+ Fe_3Zr + Fe_2Nb_(0.4)Zr_(0.6). The crystalline process of Fe_(77) Co_4 Zr_7 Nb_2 B_(10)is the same as Fe_(75) Co_6Zr_7 Nb_2 b_(10): amorphous→amorphous + α - Fe→α - Fe + Fe_3Zr→α - Fe + Fe_3 Zr + Fe_2 Nb_(0.4)Zr_(0.6). Increasing Co content restrains the nucleation of α-Fe and makes Fe_3Zr precipitate easy after annealing. The changing trends of magnetic properties of Fe_(81-x) Co_x Zr_7Nb_2 B_(10)(x = 2, 4, 6) alloys are the same with increasing annealing temperature. Annealed below 530℃, special saturation magnetization (M_s) changes a little. After 530℃, M_s increases sharply. Annealed at 530℃, coercivity (H_c) reaches the minimum. After 530℃, H_c increases with increasing the annealing temperature.
