本文研究了(Fe0.78Si0.09B0.13)100−xZrx(x=0、1和2)非晶合金。实验结果表明，少量添加Zr可以提高铁基合金的热稳定性。带材的热收缩过程主要取决于结晶过程。随着Zr含量（cZr）的增加，从X射线衍射图推导出的最近邻距离（dexp）与估计最近邻距离dcal之间的差（Δd）、起始结晶温度（Tx）、降低结晶温度（Trx）、第一次结晶的表观活化能（Ep1）以及非晶带的膨胀系数差（Δα） Fe基非晶合金的(αamor)和完全结晶对应物(αcryst)先增加后减少，这与饱和磁化强度(Ms)的变化相反。这些参数的变化可以用非晶带材与平衡状态的偏离程度来解释。除了M-T测量之外，铁基非晶合金的居里温度（Tc）还可以分别通过差示扫描量热曲线和膨胀曲线中的凸点温度和拐点温度（Tc，dscan和Tk）来缩放，随着cZr的增加，居里温度呈现出轻微下降的趋势。
The (Fe0.78Si0.09B0.13)100−xZrx(x=0, 1 and 2) glassy alloys have been investigated in this paper. The experimental results show that the minor addition of Zr can improve the thermal stability of the Fe-based alloy. The thermal contraction process of the ribbons is mainly dependent on the crystallization process. With increasing Zr content (cZr), the difference (Δd) between the nearest neighbor distance (dexp) deduced from the X-ray diffraction pattern and the estimated nearest neighbor distance dcal, the onset crystalline temperature (Tx), the reduced crystalline temperature (Trx), the apparent activation energy (Ep1) for the first crystallization, and the difference (Δα) between the expansion coefficients of amorphous ribbons (αamor) and fully crystallized counterparts (αcryst) of the Fe-based glassy alloys first increase and then decrease, which is opposite to the change of the saturation magnetization (Ms). The variation of these parameters can be explained by the deviation degree from the equilibrium state of the amorphous ribbons. Besides the M–T measurement, the Curie temperature (Tc) of the Fe-based glassy alloys can also be scaled by the bump and inflection temperatures (Tc,dscand Tk) in differential scanning calorimetric and dilatometric curves, respectively, showing a slight decreasing tendency with increasing cZr.
