Abstract

The stress-strain curves of Zr-based bulk metallic glass (BMG) were measured at very high strain rates in the supercooled liquid region (SLR) using a uniaxial compression test. For this purpose, the composite samples consisting of Zr-based metallic glass particles embedded in the crystalline nickel matrix were prepared in order to avoid rapid failure of the BMG alloy. The stress-strain curves of the BMG alloy were calculated using the data of composite samples. The strain rate sensitivity m = ∼0.1 of the present BMG alloy was determined at strain rates ranging from 100 to 10 1 s-1.
