Abstract

Intermetallic compounds and ordered phases in the Ti-Ni, Ti-Fe, Re-Ta, and Mo-Ni systems became amorphous after high energy, ion irradiation. Compounds in the Ni-Al and Fe-Al systems remained crystalline and formed dislocation networks after similar irradiation. The ease of amorphous formation correlated best with the lack of solubility within the phase field. The high internal energy of the defect state in these limited solubility alloys is believed responsible for the tendency to transform to an amorphous state. A correlation with other properties such as atom size ratio or outer electron concentration was not found.
