研究了Co替代Fe对（Fe，Co）-Ga-（P，C，B，Si）系统非晶形成能力和磁性的影响。研究了（Fe_（1-x）Co_x）（73）Ga_4P_（11）C_5 B_4Si_3的玻璃形成能力。Fe_（73）Ga_4P_（11）C_5 B_4Si_3的玻璃态合金棒的最大直径（d（max））为3.0 mm，（Fe_（0.8）Co_（0.2））（73）Ga_4P_（11）C_5 B_4Si_3的最大直径（d（max））为5 mm。然而，该合金系统的玻璃形成能力下降，进一步增加钴含量。（Fe0.8Co0.1）（73）Ga 4P 11 C5 B4 Si 3的饱和磁化强度为1.26 T，（Fe0.85Co0.15）（77）GaP10C5B3.5Si2.5的饱和磁化强度为1.40 T。（Fe，Co）-Ga-P-C-B-Si合金的高玻璃体积分数似乎是由于Co在晶化过程中的再分布所必需的。(c)2006 Elsevier B.V保留所有权利。
The replacement effect of Co for Fe on the glass-forming ability (GFA) and magnetic properties in the (Fe, Co)-Ga-(P, C, B, Si) systems were investigated. The glass-forming ability of (Fe1-xCox)(73)Ga4P11C5B4Si3 (numbers indicate at.%) alloys increased significantly by the addition of an optimum amount of Co. The maximum diameter of the glassy alloy rod (d(max)) was 3.0 mm for Fe73Ga4P11C5B4Si3 and increased to 5 mm for (Fe0.8Co0.2)(73)Ga4P11C5B4Si3. However, the glass-forming ability of this alloy system decreases with further increasing Co content. The saturation magnetization was 1.26 T for (Fe0.8Co0.1)(73)Ga4P11C5B4Si3 and 1.40 T for (Fe0.85Co0.15)(77)GaP10C5B3.5Si2.5. The d(max) for the latter alloy was 3 mm. The high GFA of (Fe, Co)-Ga-P-C-B-Si alloys seems to result from the necessity of the redistribution of Co for the progress of crystallization. (c) 2006 Elsevier B.V All rights reserved.
