Abstract:

Ti-based metallic glasses were subjected to a 20 MeV Cl4+ ion radiation under liquid-nitrogen cooling.
Their responses, as well as effects of the electronic excitation and nucleus-nucleus collision were evaluated. The collision cascade during irradiation typically changes the structure by increasing the liquid-like
zone/cluster, or the content of the free volume. However, along the ion incident depth, the structure
change is inhomogeneous. Numerous whiskers appear and aggregate on the side of the irradiation surface, which are several micrometers away from the edge. This corresponds with the maximum collision
depth obtained by the Monte Carlo simulation, where nuclear loss plays a dominant role. Moreover,
the liquid-like zone continually forms, which add to the whiskers growth and subsequent self-healing.
Results suggest that the irradiation-induced local shear stress combines with the well-localized liquidlike zone results in the observed phenomena. This study demonstrates that metallic glasses have high
morphological instability under ion irradiation, which assets can pave new paths for their further applications.
