Fe43M5Cr15Mo14C15B6Y2（M= Mn、Co、Ni和Cu，单位为at.%）采用吸铸法合成了大块金属玻璃（BMG），并利用X射线衍射、差示扫描量热仪和振动样品磁强计技术对这些玻璃的玻璃形成能力（GFA）、显微结构、热性能和磁性能进行了广泛的研究。在四种BMG合金中，Fe43Ni5Cr15Mo14C15B6Y2的矫顽力最低，饱和磁化强度、居里温度、有效磁矩和GFA最高。相比之下，Fe43Mn5Cr15Mo14C15B6Y2的磁性能最差，其矫顽力最高，饱和磁化强度、居里温度和有效磁矩最低。Fe43Cu5Cr15Mo14C15B6Y2的热稳定性和GFA最低。所观察到的这些BMG合金的热，结构和磁性能的BMG合成的动力学和不同的铁磁，亚铁磁和反铁磁相的形成进行了讨论。
Fe43M5Cr15Mo14C15B6Y2(M= Mn, Co, Ni, and Cu in at.%) bulk metallic glasses (BMGs) are synthesized using the suction casting technique, and the glass-forming ability (GFA), microstructure, and thermal and magnetic properties of these glasses are extensively examined using X-ray diffraction, differential scanning calorimeter, and vibrating sample magnetometer techniques. Among the four BMG alloys, Fe43Ni5Cr15Mo14C15B6Y2exhibits the lowest coercivity and the highest saturation magnetization, Curie temperature, effective magnetic moment, and GFA. By contrast, Fe43Mn5Cr15Mo14C15B6Y2presents the poorest magnetic properties, such as the highest coercivity and the lowest saturation magnetization, Curie temperature, and effective magnetic moment. Fe43Cu5Cr15Mo14C15B6Y2demonstrates the lowest thermal stability and GFA. The observed thermal, structural, and magnetic properties of these BMG alloys are discussed in terms of the kinetics of BMG synthesization and the formation of different ferromagnetic, ferrimagnetic, and antiferromagnetic phases.
