Exponential decay of shearing stress during jerky flows in a Zr-based bulk metallic glass
Source abstract
Abstract
Presently, an exponential decay of shearing stresses with the time during jerky flows in a Zr-based bulk metallic glass is revealed. The flow stresses with the time satisfy the following equation: σ = A · e−B · x, where A = −158.24*exp ( − N/47.60) + 1939.63 (N = 1, 2, 3…), and the mean value of obtained B is −0.13 with a Normal distribution. During jerky flows, the viscous shearing layer is formed, and the exponential decay of shear banding is present. The evolvement of shear bands is explained by the consumption of free volumes during flows.
