采用铜模铸造法在Cu42-xZr42 + xAg8Al8系统中制备了具有高非晶形成能力的Cu-Zr基块体非晶合金。在该合金体系中可以容易地获得直径为10 mm的块体非晶合金。此外，通过铜模铸造形成Cu 40 Zr 44 Ag 8Al 8、Cu 38 Zr 46 Ag 8Al 8和Cu 36 Zr 48 Ag 8Al 8合金的15 mm玻璃合金棒。这些玻璃态合金表现出超过1850 MPa的高断裂强度，杨氏模量约为115 GPa。(c)2006 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
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.
