Observation of etched tracks in an amorphous metal. C. Trautmann, S. Andler, W. Brüchle, R. Spohr, M. Toulemonde. Radiation Effects and Defects in Solids, vol. 126, pp. 207-210, (1993).

Latent tracks in amorphous metallic Fe81Bi13.5Si3.5C2 were selectively etched in 0.1 to 0.8 n HCl and in 0.04 n FeCl3. Etch pits with cone opening angles around 60° were observed. Tilted ion beams lead to tilted tracks.
