    • Abstract
  • The temperature rise of 6063 aluminum alloy during hot compression was studied by hot compression test conducted on Gleeble-1500 thermal simulator with strain rates of 0.01-10 s-1 at 400-520℃. Considering the effect of heat conduction and heat radiation, the influence of deformation temperature, strain rate and strain on the adiabatic correction factor were investigated and the equation of material deformation temperature rise was optimized. The temperature rise during hot compression at medium strain rates was corrected. The results show that adiabatic correction factor decreased with the increase of strain. The higher deformation temperature and strain rate were, the greater adiabatic correction factor was. Heat conduction and heat radiation had a significant influence on temperature rise during alloy deformation. The deformation temperature rise after correction had a nonlinear relationship with strain. Temperature changing curve calculated was almost the same with that measured and the average error was less than 3%.
