- Abstract
Uniaxial compression tests of Mg54Y11Ag7Cu28 metallic glass were performed in the supercooled liquid region (SCLR) (468 K) at a strain rate range of 5 × 10−4 to 2 × 10−3 s−1. In the course of testing, shear thickening behavior was observed, where the magnitude of the peak stress increases with increasing initial strain rate. The deformation behavior of the glassy metal is discussed with emphasis on the commonly reported stress overshoot, strain softening behavior, and the previously unreported shear thickening behavior observed.
