Abstract
This paper discusses the effect of pre-strain on the creep behaviour and constitutive modelling of titanium alloy Ti-3Al-5Mo-5V-8Cr sheets. A set of uniaxial tensile creep tests at different pre-strains and different stresses were carried out to analyse the creep behaviour of titanium alloy sheets. The results show that pre-strains have significant influence on the creep behaviour which was opposite to the effect of stress. And based on the experiment results, a modified Garofalo creep constitutive model was established which can illustrate the creep aging behaviour of titanium alloy Ti-3Al-5Mo-5V-8Cr sheet at 500°C under different stresses and different pre-strains very well.
