Abstract
The high-temperature deformation behavior of the as-forged TC17 titanium alloy was studied based on the results of thermal compression simulation tests. Additionally, the effects of strain rate, temperature and true strain on the flow stress were analyzed using orthogonal experimentation and variance analysis. The results indicated that all deformation parameters exerted significant influence on flow stress, with temperature and strain having the largest and least influence, respectively. Thereafter, a constitutive equation based on modified nonlinear regression was proposed. The error analysis results showed that the flow stress of the as-forged TC17 alloy could be predicted by the obtained constitutive equation. The effect of deformation parameters on the microstructure was investigated by EBSD and TEM.
