摘要：

Melt thermal history is highly heritable to the structure of metallic glass frozen by rapid quenching liquid. In this paper, the influences of melt thermal history above liquidus temperature on magnetic properties and thermal stability have been systematically investigated in Fe75Si9B12C4 amorphous alloy. The results show that both magnetic properties and thermal stability of the alloy show a non-overlapping feature for the alloys undergone melt heat preservation during heating and cooling process, respectively. It was found that melt thermal history can significantly affect the structural change of the alloy, and thus results in hysteresis behaviors of magnetic properties and thermal stability through changing degree of amorphization. These findings could help under-stand the melt thermal history and design preparation technology of soft magnetic amorphous alloys.
