The hot deformation of TA15 titanium alloy was studied by the compression test on Gleeble-3800 thermal simulation equipment. true stress-strain curves at temperature 1123-1223K and strain rate 0.001-1s -1 were obtained.. results show that flow stress increases with decreasing temperature, as increases. And process is accompanied work hardening dynamic recovery recrystallization. Based alloy, Ar...

The relaxation processes of a wide variety of soft materials frequently contain one or more broad regions of power-law–like or stretched exponential relaxation in time and frequency. Fractional constitutive equations have been shown to be excellent models for capturing the linear viscoelastic behavior of such materials, and their relaxation modulus can be quantitatively described very generally...
