摘要：
Isothermal compression of TC11 alloy at the deformation temperatures ranging from 1023 to 1323 K with an interval of 20 K, the strain rates of 0.001, 0.1, 1.0, and 10.0 s(-1), and the height reductions of 50% and 70% was conducted on a Gleeble-1500D thermomechanical simulator. According to the experimental results, the isothermal compression and the processing maps of TC11 alloy at different strains were drawn by using the dynamic material model (DMM). Based on the processing maps, the proper forging parameters, including a combination of deformation temperature and strain rate, vary with the strain in different phases of TC11 alloy.
