Abstract

We studied the role of thermal spike in nanocrystallization of Cu₅₀Zr₄₅Ti₅ metallic glasses after 1 MeV Cu ion irradiation at room temperature. Nanocrystals of Cu₁₀Zr₇ and CuZr₂ phases are formed after the ion irradiation. The study suggests that thermal spike formation and subsequent quenching are too fast to allow direct structural transformation in the damage cascade regions. The overall irradiation effects are caused by enhanced atomic mobility due to increased excessive free volume.
