Abstract

Size limitation is one of the bottleneck issues to bulk metallic glasses (BMGs). Selective laser melting (SLM) uses localized, point-specific, high energy beam to manufacture. By applying SLM to an Fe-based BMG, a record-large, fully amorphous sample (Ø45 mm × 20 mm) has been produced into good mechanical properties. SLM process map is constructed and finite element simulation is employed for the study. The rapid cooling rate during SLM, a sufficiently short exposure time to high temperature, and the good thermal stability of the alloy are the key points to form such superlarge, quality BMG. As-printed, demonstrative part is present, and the implications of the results are addressed.
