摘要

利用X射线衍射（XRD）和差热分析（DSC）方法

研究分析了Zr元素对Fe-Al-Ga-P-C-B-Si系合金非晶形成能力和热稳定性的影响。试验结果表明

含少量（≤2.0%

摩尔分数

下同）Zr的合金仍表现为非晶态

Zr含量为1.0%时的XRD图像表明为非晶态

而DSC曲线没有显示出明显的玻璃转变

这是初始晶化相的放热峰掩盖了DSC上的玻璃转变;当Zr含量为0.5%和2.0%时

DSC曲线具有明显的玻璃转变温度Tg和较大的过冷液相区ΔTx

其晶化放热峰位置明显地向高温区域移动

表明具有较大的玻璃形成能力（GFA）和热稳定性。同时

用参数γ验证了合金的热稳定性。

Abstract

Effects of Zr on glass forming ability and thermal stability of Fe-Al-Ga-P-C-B-Si amorphous alloy have been analyzed by XRD and DSC.The experimental results reveal that the alloy retains amorphous features with Zr content less than 2.0%（atom percentage）.Although the DSC curve had no obvious glass transition

the XRD observation indicated that the alloy with 1% Zr content（atom percentages）

which is attributed to the exothermic peak of initial crystalline phase

had blanketed glass transition.DSC curves of the alloy with 0.5% and 2% Zr contents presented apparent glass transition temperature and wider undercooled liquid region

respectively

and the position of crystalline exothermic peak shifted towards higher temperature area

which reveals that the alloy have high glass forming ability and thermal stability.In addition

the thermal stability was verified by the parameters γ.
