采用铜模铸造法在Fe 43 Cr 16 Mo 16（C，B，P）（25）系统中在较宽的成分范围内合成了最大厚度（t（max））为1.0-2.7 mm的大块非晶合金。它们表现出40-90 K的大的过冷液体区域（Δ T（x））和0.54-0.60的高的约化玻璃化转变温度（Tg/T-1），表明高的玻璃形成能力（GFA）和高的过冷液体的热稳定性。玻璃形成的临界冷却速率估计为10（2）K s（-1）的数量级。大块非晶合金在腐蚀性强的HCl溶液中具有很高的耐蚀性。合金元素P对耐腐蚀性具有有益的影响。(C)2002 Acta Materialia Inc.由爱思唯尔科技有限公司出版。保留所有权利。
Bulk metallic glasses with a maximum thickness (t(max)) 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 (DeltaT(x)) of 40-90 K and a high reduced glass transition temperature (T-g/T-l) 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 10(2) K s(-1). The bulk metallic glasses exhibited high corrosion resistance in aggressive HCl solutions. The alloying element P has a beneficial effect on corrosion resistance. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
