Abstract

Isothermal compression tests were conducted at various temperature and strain rate combinations over the hot working range (880 to 1040°C and 0.01 to 10.0 s-1) of TC11 alloy. Based on the experimental data, the strain rate sensitivity factors m were calculated. Both the efficiency of power dissipation η and the instability parameter ζ were computed, and then processing maps incorporated instability maps were accordingly established at strains of 0.1, 0.3 and 0.6. A method to optimize the forging process of Titanium alloy blisk was proposed based on the processing map. The optimized process of TC11 alloy blisk was achieved using the proposed method and was verified by numerical simulation and experiment. The results showed that this optimal process is applicable to produce blisk with duplex structures.
