摘要
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 similar to 370 degrees C. This bulk metallic glass exhibits benchmark characteristics of thermoplastic processing and will hopefully broaden the engineering applications of amorphous metals.
