Heat Treatment Effect on Amorphization and Structure of Fe_(80)B_(13)Si_5C_2 Melt in Ultrarapid Quenching

摘要

X-ray diffraction, differential scanning calorimetry, and differential thermal analysis are used to investigate the superheating-temperature effect of a Fe_(80)B_(13)Si_5C_2 melt on its supercooling, amorphization ability, and the crystallization processes of rapidly quenched alloys during subsequent heating. The melt is found to reach the maximum supercooling and the highest amorphization ability after heating in the temperature range of 1450-1480℃. It is revealed that, when heated to 1500°C, the supercooling and amorphization ability of the melt decrease sharply.
