摘要
设计并采用快速淬火法制备了低成本、高饱和磁化率和低矫顽力的新型 Fe83 - xSi2.5B12P2.5Cx (x = 0, 0.5, 1.0, 1.5, 2.0 at%)非晶软磁体系。研究了 C 对合金体系的非晶成型性、热稳定性和软磁性能的影响。结果表明,小原子 C 的加入能促进合金形成致密的原子结构,从而促进非晶态成形性的提高。随着 C 含量的增加,两个结晶峰之间的温度间隔先增大后减小。当 C 含量为 1.0 at% 时,ΔT(Tx2-Tx1)达到最大值,约为 109.9 ℃,这有利于提高合金的热稳定性和软磁性能。随着 C 浓度的升高,Bs 呈现先升高后降低的模式,而矫顽力则呈现相反的变化。当 C 含量为 1.0 at% 时,合金的 Bs 达到最高值 1.78 T,矫顽力达到最好的 14.055 A/m。这些结果为设计和改进用于非晶电机工业应用的高 Bs 非晶软磁材料做出了重要贡献。
The role of C content on the glass-forming ability and magnetic properties of FeSiBPC amorphous alloys
The new type of Fe83 − xSi2.5B12P2.5Cx (x = 0, 0.5, 1.0, 1.5, 2.0 at%) amorphous soft magnetic system with low cost, high saturation magnetization and low coercivity were designed and prepared by means of rapid quenching. The effect of C on the amorphous formability, thermal stability, and soft magnetic properties in the alloy system were studied. Results suggest that the addition of small atom C can promote the formation of densely atomic structure of alloy, thereby promoted the enhancement of amorphous formability. With the increase of C content, the temperature interval between two crystallization peaks increases first and then decreases. When C content is 1.0 at%, ΔT (Tx2-Tx1) reaches the maximum value, of about 109.9 ℃, which is beneficial to enhance the thermal stability and soft magnetic properties. As the concentration of C is raised, the Bs exhibit a pattern of increases followed by a subsequent decrease, while coercivity changes in the opposite way. When the C content is 1.0 at%, the Bs of the alloy reaches the highest value of 1.78 T and the coercivity exhibits the best which is 14.055 A/m. The results offer important contributions to the design and advancement of high Bs amorphous soft magnetic materials for industrial applications involving amorphous electric motors.
