Thermal Deformation Mechanism and Microstructure Evolution of TA15 Titanium Alloy near the Phase Transition Point AITranslate
Abstract AITranslate
Isothermal compression experiments of TA15 titanium alloy were conducted on Gleeble-3500 thermal simulator with strain rate of 1~0.01s-1 and deformation temperature of 900~1 050 ℃.The results show that thermal deformation behavior of TA15 titanium alloy near the phase transition point can be described by a constitutive equation in hyperbolic sine function form including Zparameter.Within the experimental parameter range,with deformation temperature and strain rate gradually increasing,microstructure and thermal deformation mechanism of TA15 titanium alloy change,resulting in deformation activation energy increased firstly and then decreased.Thermal processing map and deformation microstructure analysis show that when thermal deformation happens in the upper part of two-phase region(about 950℃)at a lower strain rate(0.1~0.01s-1),the energy dissipation efficiency of the alloy is higher and its microstructure has uniformly distributed fine grains due to complete dynamic recrystallization.
