Microhardness, hot hardness, uniaxial compression, and notched bending experiments were conducted on Cu60Zr20Hf10Ti10 bulk metallic glass (BMG). This Cu-based BMG possesses near theoretical strength but essentially zero compressive ductility at room temperature. Notch toughness values in excess of 65 MParootm were obtained, while significant softening was obtained near T-q (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
