摘要：
Bulk glassy alloys in Ni-Nb-Ti-Hf system were formed at composition of Ni60Nb20Ti12.5Hf7.5 by copper mold casting. The supercooled liquid region and reduced glass transition temperature were 60 K and 0.609, respectively. The bulk glassy alloy exhibits high compressive fracture strength of 3180 MPa and good ductility. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
