Abstract: The hot deformation behavior of C61300 aluminum bronze at deformation temperatures of 600 °C – 900 °C and strain rates of 0.001 s-1 – 1 s-1 was studied by Gleeble-3500 thermo-mechanical simulator. Based on the hot compression test data, true stress–true strain curves of C61300 under different deformation conditions were obtained, and a constitutive equation describing the alloy’s hot deformation behavior was established through linear regression. The results show that flow stress decreases with increasing deformation temperature and increases with increasing strain rate.
