Simple microreplication experiments carried out in open air using relatively low applied pressures demonstrate superior thermoplastic processability of newly designed bulk metallic glass. It is the microformed impression of a United States dime coin (see figure) made on the surface of metallic glass wafers at ∼370 °C. This bulk metallic glass exhibits benchmark characteristics of thermoplastic processing and will hopefully broaden the engineering applications of amorphous metals.
