Abstract

Crystallization of amorphous thin films of Ni-Zr, Ni-Ti and Fe-Zr during heavy-ion irradiation with 500 keV Xe+ ions and without irradiation has been studied. The crystallization temperatures are found to be significantly lowered by ion irradiation. In particular, this effect is pronounced for compositions close to elemental ones, where the crystallization is found to take place through nucleation and growth of terminal solid solutions. A close agreement is found between the onset temperature of crystallization and the upper temperature limit for amorphization of a crystalline elemental multilayer with the same heavy-ion irradiation.
