摘要：

Cu-Zr-based bulk glassy alloys are synthesized with high glass-forming ability in a Cu42-xZr42+xAg8Al8 system by copper mold casting. Bulk glassy alloys with a diameter of 10 mm can be easily obtained in this alloy system. Also, 15-mm glassy alloy rods are formed for the Cu40Zr44Ag8Al8, Cu38Zr46Ag8Al8 and Cu36Zr48Ag8Al8 alloys by copper mold casting. These glassy alloys exhibit high fracture strengths of over 1850 MPa with Young's moduli of about 115 GPa. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
