| Abstract: | This study investigated the hot deformation behavior of the Cu–9Ni–6Sn–0.6Cr alloy under different deformation conditions through isothermal hot compression experiments. The alloy was tested under four different strain rates (1 s⁻1, 0.1 s⁻1, 0.01 s⁻1, and 0.001 s⁻1) and four deformation temperatures (750 °C, 800 °C, 850 °C, and 900 °C). The microstructural evolution of the alloy was analyzed, and its constitutive model and hot processing map were developed based on the peak stress. The results show that the alloy exhibits a hot deformation activation energy of 227.754 kJ/mol. The material demonstrates a strain hardening index of 8.0408, with a strong correlation (R2 = 0.96065) observed between empirical measurements and theoretical predictions. The constructed hot processing map reveals that the alloy exhibits optimal formability under specific thermomechanical conditions, particularly within the 830–885 °C temperature range and at strain rates of 0.001–0.005 s⁻1.
