Fig. 2: Anomalous temperature dependence of the elastic limit.
From: Anomalous temperature dependence of elastic limit in metallic glasses
a Stress–strain curves of the tensile loading tests at different temperatures in the y-direction up to the elastic limit (onset of inelasticity), then unloading back to zero stress. The elastic strain is removed from the total strain to reveal the ST events. Curves at non-zero temperatures are shifted to help with visualization. Two additional reversible cyclic loading tests are performed below the elastic limit at 5 K (the third curve, up to 0.3% strain) and 20 K (the seventh curve, up to 0.58% strain). b The simulated elastic limit \({\varepsilon }_{\lim }\) as a function of temperature. The solid (red) and dashed (green) arrows indicate the normal and anomalous temperature effects on \({\varepsilon }_{\lim }\).
