Abstract
AbstractWe investigated the deformation behavior of the supercooled liquid in a La55Al25Ni20 (at.%) metallic glass ribbon that has a wide supercooled liquid region of 65 K before crystallization. The deformation of the metallic glass was divided into three types, namely, homogeneous deformations with and without a stress overshoot and an inhomogeneous deformation. The supercooled liquid above the glass transition temperature (Tg) exhibited a Newtonian viscosity and superplastic-like behavior during isothermal tensile deformation. The metallic glass was elongated as much as 1000 % at high strain rates ranging from 10−2 s−1 to 10o s−1 without embrittlement. The maximum elongation to failure was in excess of 1800 % at a strain rate of 1.7×10−1 s−1 and at 503 K (Tg+20 K, 0.71Tm) under about 40 MPa.
