ABSTRACT

A combined experimental and simulation approach was employed to investigate the mechanical properties of TC4 titanium alloy at elevated temperatures. A high-temperature tensile testing system integrated with digital image correlation (DIC) technology was established to conduct tensile tests at nine temperatures ranging from 26 ℃ to 750 ℃. True stress–strain curves were obtained, from which key mechanical parameters—including elastic modulus, yield strength, tensile strength, Poisson's ratio, strain hardening exponent (n-value), and plastic strain ratio (r-value) were derived. The results reveal that as temperature increases, elastic modulus, yield strength, and tensile strength decrease significantly, whereas Poisson's ratio increases, indicating enhanced plastic deformation capability. Both the n-value and r-value exhibit an overall decreasing trend, reflecting reduced resistance to plastic instability and thinning. Furthermore, finite element simulations were performed and the simulated stress–strain responses were in good agreement with the experimental results. The developed temperature–displacement coupling model effectively validates the reliability of the experimental measurements and parameter calculations.
