Stress-strain curves of Vit105 samples tested at , and at a strain rate of . Inset: individual serrations, plotted as relative load vs. time, showing an increase in load drop duration with decreasing temperature.
Mean stress drop and mean strain burst magnitude as a function of temperature, revealing a decrease in stress drop size (for ) and a weak increase in strain burst magnitude with decreasing temperature.
SDJ velocity as a function of engineering strain for the samples tested at and . At , the sample shows a distinct increase in SDJ velocity, coinciding with a progressive decrease in flow stress level (see Fig. 1). At , where the flow curve in Fig. 1 exhibits a constant stress level, the SDJ velocity also remains constant as a function of strain.
SDJ and SFP velocities as a function of inverse temperature, showing Arrhenius-type behavior.
