摘要：
Thermal and magnetic properties of Al, Sri and C modified Fe-P-Si-B amorphous alloys with compositions Fe80-x-y-z AlxSnyP12-zSi4B4Cz. (in at%, x = 3-5, y = 1-7, z = 0-6) were investigated. By suitable replacements of Fe by Al/Sn, and P by C in these alloys, the glass-forming ability is greatly enhanced. The super-cooled liquid region and reduced glass transition temperature were examined and compared to the modified alloys. Properties of Fe74Al4Sn2P12-zSi4B4Cz amorphous alloys are typically, with increasing z: saturation magnetization 1.28-1.38T, coercive force around 40 A/m, Curie temperature of 547-595K, the electrical resistivity decreases from 181 to 168 muOmega-cm. Magnetic inductance of the cast cores were also reported. (C) 2004 Elsevier B.V. All rights reserved.
