  基于热力学模型的Fe-Er合金玻璃形成能力分析

  摘要：

  Fe-Er相图及其所有相的热力学性质均通过自洽分析进行评估。为了完善Fe-Er系统中相平衡的数据，在10％至40％的Er浓度范围内进行了研究。熔体热力学性质的温度-浓度依赖性是使用理想的关联溶液模型来表示的。得到了各相的热力学参数，计算结果与现有实验数据相符。研究了液态Fe–Er合金的热力学性质与其非晶化趋势之间的相关性。结果表明，通过熔融淬火制备的非晶态合金的组成与Fe 3 Er和FeEr占优势的浓度范围一致。2个具有较大负熵形成的关联组。

  The phase equilibria of Er-Fe-Cr system at 773 K were investigated by X-ray powder diffraction (XRD), differential thermal analysis (DTA), and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). The isothermal section consists of 8 single-phase regions, 14 two-phase regions and 7 three-phase regions. The homogeneity range of the ternary compound ErFe12 Cr-x(x) was determined to be x = 1.6-3.0. The maximum solid solubilities of Cr in ErFe2, ErFe3, Er6Fe23, Er2Fe17, and Fe are about 8.2, 1.2, 15.6, 9.6 and 13.8 at.% Cr, respectively, and the solubility limit of Fe in Cr is about 13.3 at.% Fe. The microwave absorbing properties of the intermetallic compounds in Er-Fe-Cr system were determined. All the samples exhibited good absorbing property in the X-band (8-12 GHz). With a coating thickness of d = 2.0 mm, the minimum return loss at the absorption peak frequency of the ErFe2, ErFe3, Er6Fe23, Er2Fe17 and ErFe10Cr2 are -19.66 dB at 9.6 GHz, -29.57 dB at 8.16 GHz, -35.04 dB at 12.72 GHz, -22.72 dB at 9.76 GHz and -13.51 dB at 11.2 GHz, respectively.

  The isothermal sections of the phase diagram of Er-Fe-Sn ternary system were constructed at 770 and 670 K in the whole concentration range using X-ray and metallographic analyses. Component interaction in the Er-Fe-Sn system at 670 K results the existence of two ternary compounds, ErFe(6)Sn(6) (YCo(6)Ge(6)-type) and Er(5)Fe(6)Sn(18) (Tb(5)Rh(6)Sn(18)-type), while at 770 K only one intermediate ErFe(6)Sn(6) phase was observed. The existence of the interstitial solid solution ErFe(x)Sn(2) (up to 5 at.% Sn) was found at both temperatures. (C) 2010 Elsevier B.V. All rights reserved.

  In order to determine the existence of phases and relationships in the Er-Fe-Mn system at 773 K, we have carried out this work mainly by X-ray powder diffraction with the aid of differential thermal analysis and have obtained the conclusions below. The existence of seven binary compounds ErFe2, ErFe3, Er6Fe23, Er2Fe17, ErMn12, Er6Mn23, ErMn23 and one intermediate solid solution gamma(Fe center dot Mn) have been confirmed in this system. Er6Fe23 and Er6Mn23 form continuous solid solution Er-6 (Fe23-X Mn-X) (0 <= X <= 23). At 773 K, the maximum solid solubility of Fe in alpha Mn, ErMn12, ErMn2 phases and Mn in ErFe2, Er2Fe17, alpha Fe phases are about 31, 69, 13 at% Fe and 47, 28, 8 at% Mn, respectively. The homogeneity range of gamma(Fe center dot Mn) phase extended from about 34 at% Mn to 52 at% Mn. The maximum solid solubility of Er in gamma(Fe center dot Mn) phase is about 2 at% Er. The isothermal section consists often single-phase regions, sixteen two-phase regions and seven three-phase regions. No ternary compounds were observed at 773 K in this system. (C) 2008 Elsevier B.V.
