基于能量守恒法,提出了研究块体非晶合金晶化机制研究的新方法。利用DSC方法和Kissinger式计算了块体非晶合金Zr53.7Ni9.4Cu28.5Al8.4在连续升温过程中的晶化激活能。通过对该块体的激光点热源加热试验,验证了该晶化机制模型的正确性。结果表明,Zr53.7Ni9.4Cu28.5Al8.4块体非晶的晶化激活能为220 kJ/mol,所提出的方法可定性地用于该块体非晶晶化机制研究。
Based on the energy conservation method, a new method to study the crystallization mechanism of bulk amorphous alloys was proposed. The crystallization activation energy of bulk amorphous alloy Zr53.7Ni9.4Cu28.5Al8.4 during continuous heating was calculated by DSC and Kissinger equation. Through the heating test of the laser spot heat source of the block, the correctness of the crystallization mechanism model was verified. The results show that the crystallization activation energy of Zr53.7Ni9.4Cu28.5Al8.4 bulk is 220 kJ / mol. The proposed method can qualitatively be used to study the mechanism of amorphous crystallization.
