The surface of Zr{sub 41.25}Ti{sub 13.75}Cu{sub 12.5}Ni{sub 10.0}Be{sub 22.5}, a bulk metallic glass prepared by RF induction melting, has been imaged using atomic force microscopy. The untreated surfaces were very smooth; features were no higher than 3 nm over a 10{times}10 {mu}m region, comparable to many polished surfaces. Two types of microstructure were also observed; periodic striations forming either a striped or a checkered structure were present, with wavelengths between 1 and 2 {mu}m, and amplitude of approximately 2 nm; in other cases, {open_quote}{open_quote}cracked mud{close_quote}{close_quote}-like patterns were observed. These microstructures could be related to strain-induced surface roughening; preliminary calculations are presented that are consistent with this hypothesis. {copyright} {ital 1996 Materials Research Society.}
