本文通过对快凝Ｎｉ７４Ｓｉ１０Ｂ１６非晶合金不同温度与时间下真空热处理样的差热扫描量热分析与Ｘ射线衍射分析发现：热处理未改变试样的非晶性时，热处理前后试样的晶化温度保持不变；当非晶基体中析出初晶Ｎｉ颗粒时，热处理样的初始晶化温度下降；进一步析出Ｎｉ３Ｂ等晶化相时，热处理样的晶化温度反而上升。根据以前建立的高类金属含量Ｎｉ基非晶合金的晶化机制［１～２］，本文对此给出了比较合理的解释。
In this paper, differential scanning calorimetry and X-ray diffraction analysis of the rapidly solidified Ni74Si10B16 amorphous alloy at different temperatures and times were used to find out that the crystallization temperature before and after heat treatment did not change The initial crystallization temperature of the heat-treated samples decreased when the primary Ni particles precipitated in the amorphous matrix. When the precipitated Ni3B phase was further precipitated, the crystallization temperature of the heat-treated samples increased instead. According to the previously established high-class metal content Ni-based amorphous alloy crystallization mechanism [1 ~ 2], this article gives a more reasonable explanation.
