Abstract

Zr-based bulk metallic glass composites containing dendrites were fabricated by the Bridgman solidification. Quasi-static and dynamic deformation behaviors of the composites were investigated. It was found that fracture strength of the composites did not change obviously. However, under quasi-static compression, the stress-strain curves show obvious elastic and plastic deformations, while for the dynamic loading, it is difficult to distinguish the plastic and the elastic strain, and total strain limit is 3.6% and 5.0% for Zr_58.5Ti_14.3Nb_5.2Cu_6.1 Ni_4.9Be_11.0 and Zr_60.0Ti_14.7Nb_5.3Cu_5.6 Ni_4.4Be_10.0 alloys, respectively. The prompt failure under the dynamic loading was due to the insufficient time for the multiple shear bands to be generated. Crown
