摘　　要：利用穆斯堡尔谱和Ｘ射线衍射研究了４种Ａｌ－Ｆｅ－Ｖ－Ｓｉ－Ｍｍ合金的Ｆｅ原子组态。结果表明，添加混合稀土元素后抑制了基体合金Ａｌ－Ｆｅ－Ｖ－Ｓｉ中α－Ａｌ１３（Ｆｅ，Ｖ）３Ｓｉ弥散粒子相的析出；当稀土含量高达６ａｔ％时，形成Ａｌ－Ｆｅ－Ｖ－Ｓｉ－Ｍｍ非晶态，采用Ｖｏｉｇｔ基函数作了穆斯堡尔谱的合理拟合和分析。The iron atomic situations in Al93.3-xFe4.3V0.7Si1.7Mmx (x=0, 1, 3, 6) alloys were investigated by means of Mossbauer spectroscopy and X-ray diffraction. The results show that the appearance of bee α-Al13 (Fe, V)3Si dispersive particles existing in Al-Fe-V-Si alloy is suppressed by the addition of misch metal.A new Al-Fe-V-Si-Mm amorphous alloy is formed, which the concentration of misch metal is up to 6 at%, in the meantime, the corresponding structural analysis is made using Voigt-based fitting method.
