Abstract

Isothermal compression of the TC11 titanium alloy has been conducted on Gleebe-1500D hot-simulator at the deformation temperature ranging from 960°C to 1050°C, the strain rate ranging from 0.01s^-1 to 10s^-1, the maximal engineering strain 50%. Based on dynamic materials model (DMM) theory, the hot processing maps for TC11 titanium alloy were constructed at different strains with the data of hot compression tests. By analyzing the instability and stability regions of the processing maps and the microstructures of the specimens deformed in different regions, hot deformation mechanisms, deformation defects and optimization of hot working process for TC11 titanium alloy were investigated.
