摘要: Bulk metallic glasses with a maximum thickness (tmax) of 1.0–2.7 mm were synthesized in the Fe43Cr16Mo16 (C, B, P) 25 system over a wide composition range by copper mold casting. They exhibit a large supercooled liquid region (ΔTx) of 40–90 K and a high reduced glass transition temperature (Tg/Tl) of 0.54–0.60, indicating high glass-forming ability (GFA) and high thermal stability of the supercooled liquid. The critical cooling rate for glass formation was evaluated to be of the order of 102 K s− 1. The bulk metallic glasses exhibited …
