用Mossbauer谱学和XRD方法研究了快速凝固Al-5Fe—2Ni(原子由分数)合金的析出相.结果表明,析出相为三元化合物Al_9Fe_xNi_(2-x)(0

The precipitate in rapidly solidified Al-5Fe-2Ni alloy has been investigated by means of Mossbauer spectroscopy and X-ray diffraction.It has been identified as a ternary compound Al9FexNi(2-x)(0 < x <2) with monoclinic crystal lattice and parameters a = 0
