| Description | Journal: Iop Conference Series: Materials Science and Engineering The isothermal constant strain rate compression experiment of Ti-29Nb-13Ta-4.6Zr (TNTZ) alloy with deformation temperature of 700∼900°C and strain rate of $0.001∼1s^{-1}$ was carried out by Gleeble-3500 thermal simulator. The high temperature deformation behavior of the alloy was discussed and the thermal deformation activation energy was calculated. The hyperbolic sinusoidal constitutive model of TNTZ alloy was constructed. The results show that the flow stress of the alloy tends to be steady at high temperature and low strain rate. The constitutive model established by the Arrhenius model and modified by Zener-Hollomon parameter, which its correlation coefficient R and the average relative error E is 0.971 and 5.92%. The results predicted value for high temperature deformation behavior and agrees well with the experimental value of the alloy. |
