Abstract AI-817e and AI-8Fe-4RE (cerium, erbium, neodymium and gadolinium) alloys were rapidly solidified by the melt-spinning technique. The microstructure and phases of alloy ribbons were studied using optical metallography, SEM, TEM and X-ray diffraction techniques. The study has indicated that Re additions to AI-8Fe: (1) result in formation of an increased amount of fine microstructure region, (2) increase the hardness and stability, and (3) generally suppress the formation of needle-type Al3Fe compounds by substituting them with globular Al3Fe2RE compounds. The addition of gadolinium appears to produce the best results.
