Abstract

The stress-strain curves of Zr-based bulk metallic glass (BMG) at high strain rates were determined by the compression test at a temperature in the supercooled liquid region. Using solid metal lubricant (SML) sheets, the compression test was successfully carried out without failure up to a strain of 0.68, even at a strain rate of 10/s. The finite element method calculations were carried out for clarifying the role of the SML during compression tests. Published by Elsevier B.V.
