In this study, the formation and crystallization of the AlFeVNb₅ amorphous alloys has been investigated. The addition of Nb enhances the supercooled liquid region and glass forming ability of the Al-Fe-V amorphous alloys. The AlFeVNb₅ amorphous alloy exhibits two distinct crystallization steps and a large supercooled liquid region at more than 100 K. Kissinger and Ozawa analyses showed that the two activation energies for crystallization (E) were estimated to be 366.3 ± 23.9 and 380.5 ± 23.9 kJ/mol. Large supercooled liquid regions are expected to gain an application field of Al-based amorphous alloys.
在本研究中，对AlFeVNb₅非晶合金的形成和结晶进行了研究。铌的添加增强了Al-Fe-V非晶合金的过冷液相区和玻璃形成能力。AlFeVNb₅非晶合金呈现出两个明显的结晶步骤，并且在超过100 K的温度下具有较大的过冷液相区。基辛格和小泽分析表明，两个结晶活化能（E）估计分别为366.3±23.9和380.5±23.9 kJ/mol。较大的过冷液相区有望为铝基非晶合金赢得一个应用领域。
