利用X射线衍射 (XRD)和差示扫描量热法 (DSC)研究了在连续加热条件下非晶态Zr65Cu17 5Ni10 Al7 5合金在空气中的氧化和晶化过程。结果表明 ,在 4 5 0℃以下 ,非晶态Zr65Cu17 5Ni10 Al7 5合金表面的ZrO2 晶粒长大过程服从抛物线规律 ;当温度超过 4 5 0℃时 ,由于非晶基体内部发生晶化过程 ,阻碍了表面氧化过程的发展 ,此时ZrO2 晶粒大小满足线性规律 ,并给出了ZrO2 晶粒尺寸与温度的函数表达式。非晶态Zr65Cu17 5Ni10 Al7 5合金的晶化过程是先形成二十面体相 ,然后转变为稳定的晶化相。 The oxidation and crystallization of amorphous Zr65Cu17 5Ni10Al7 5 alloy in air were investigated by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The results show that the grain growth process of ZrO2 on the surface of amorphous Zr65Cu17 5Ni10 Al7 5 alloy obeys a parabolic law below 450 ℃. When the temperature exceeds 450 ℃, the crystallization process of the amorphous matrix hinders The development of the surface oxidation process, when ZrO2 grain size to meet the linear law, and gives the ZrO2 grain size and temperature as a function of expression. Amorphous Zr65Cu17 5Ni10 Al7 5 alloy crystallization process is the first to form icosahedral phase, and then transformed into a stable crystalline phase.
