Abstract An as-cast in situ Zr56.2Ti13.8Nb5.0Cu6.9Ni5.6Be12.5 bulk metallic glass composite with enhanced plasticity was prepared by water quenching, which contains a ductile bcc β-Zr solid solution. The β phase with a volume fraction of about 30% possesses a developed dendritic morphology. The present composite exhibits a pure plastic strain of 10.2% combined with a large elastic strain limit of 2% and a high ultimate strength of 1778MPa upon room-temperature compression. Microscopic observation shows numbers of wavelike shear bands dispersed on the surface of deformed compressive samples

Key words: water quenching as-cast in situ formed ductile dendritic crystalline phase bulk metallic glass comp
