通过结合使用 X 射线衍射 (XRD)、透射电子显微镜 (TEM) 和差示扫描量热法 (DSC) 研究了熔纺 (Zr65Al7.5Cu27.5)95Ti5 玻璃合金中的相变。结果发现，Ti的添加改变了Zr65Al7.5Cu27.5玻璃合金的结晶模式，在(Zr65Al7.5Cu27.5)95Ti5四元玻璃的初晶阶段观察到纳米级二十面体相(I相)的形成，并在进一步退火后转变为稳定的Zr2Cu型相。与Zr65Al7.5Cu27.5合金相比，进一步从活化能角度讨论了(Zr65Al7.5Cu27.5)95Ti5玻璃的结晶行为。
Phase transformation in the melt-spun (Zr65Al7.5Cu27.5)95Ti5 glassy alloy was investigated by a combined use of X-ray diffraction (XRD), transmission electron microscopy (TEM) and differential scanning calorimetry (DSC). It was found that the crystallization mode of the Zr65Al7.5Cu27.5 glassy alloy was altered by the addition of Ti, and nanometer scaled icosahedral phase (I-phase) formation was observed in the primary crystallization stage of the (Zr65Al7.5Cu27.5)95Ti5 quaternary glass, which transformed to the stable Zr2Cu-type phase upon further annealing. The crystallization behavior of (Zr65Al7.5Cu27.5)95Ti5 glass was further discussed in terms of the activation energy as compared to that of Zr65Al7.5Cu27.5 alloy.
