Abstract

The improvement effect of replacing B with C or P on the formation ability, thermal stability and magnetic properties for melt-spun (Fe_0.8Co_0.2)₈₅B_14-xSi₁M_x and (Fe_0.8Co_0.2)₈₄B_15-xSi₁M_x amorphous alloy ribbons was examined because the base amorphous alloy exhibits ultrahigh saturation magnetization (M_S) reaching 2.0 T The minor alloying by C or P causes an enhancement of its formation ability, a decrease in the onset temperature of the first-stage crystallization (T_x1) due to the precipitation of bcc FeCo phase and a slight increase in the second-stage crystallization temperature (T_x2) due to the decomposition of the residual amorphous phase, resulting in an extension of the temperature interval between T_x1 and T_x2. The annealing of their amorphous alloys causes a reduction of coercive force (H_C) and an increase of effective permeability (µ_e) at 1 kHz, though the M_S decreases slightly. The excellent soft magnetic properties of 1.98 T for M_S, 8.0 A/m for H_C and 5800 for µ_e were attained for (Fe_0.8Co_0.2)₈₅B₁₃Si₁P₁ amorphous ribbon with a thickness of 20 µm annealed for 500 s at 570 K. Their soft magnetic properties are promising for future application of the present amorphous alloys as a new high M_S soft magnetic material for electric motors.

P和C对2.0 T超高饱和磁化Fe-Co-B-Si非晶合金形成能力和软磁性能的改善

采用C或P替代B对熔融纺丝（Fe0.8Co0.2）85B14-xSi1Mx和（Fe0.8Co0.2）84B15-xSi1Mx非晶合金带的形成能力、热稳定性和磁性能的改善效果进行了研究，因为基材非晶合金具有超高的饱和磁化强度（MS），达到2.0 T。由于bcc FeCo相的析出导致第一阶段结晶开始温度（Tx1）降低，而由于残余非晶相的分解导致第二阶段结晶温度（Tx2）略有升高，导致Tx1与Tx2之间的温度间隔延长。在1 kHz时，非晶合金的矫顽力（HC）降低，有效磁导率（µe）增加，但MS略有下降。对厚度为20µm的（Fe0.8Co0.2）85B13Si1P1非晶带在570 K下退火500 s，获得了MS为1.98 T， HC为8.0 A/m，µe为5800的优异软磁性能。目前的非晶合金作为一种新型的高MS电机软磁材料，其软磁性能具有广阔的应用前景。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
