报道了一类富铝大块金属玻璃(BMG)的形成和性质。这些合金的铝含量可达40at.%，是已知的BMG中最高的。富铝BMG与共晶成分偏离较大，表现出较高的热稳定性和脆性，并具有很高的机械强度。这些富Al的BMG可能对铝基BMG具有普遍意义，并有助于理解Al在玻璃形成中的作用。(C)2008 Acta Materialia Inc.由爱思唯尔有限公司出版。版权所有。
The formation and properties of a class of Al-rich bulk metallic glasses (BMGs) are reported. The Al contents for these alloys can reach up to 40 at.%, which is the highest in known BMGs. The Al-rich BMGs deviate greatly from eutectic composition and show high thermal stability and fragility, and very high mechanical strength. These Al-rich BMGs might have implications for Al-based BMGs in general and for understanding the role of Al in glass formation. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd.
