Isothermal constant strain rate compression tests on TCll alloy in the strain rate range of 0.001～70.0 s~(-1) were conducted up to a true strain of 1.2 using the THERMECMASTOR-Z hot working simulator,at 960 and 1050℃,respectively.The characteristic of true stress-true stain curves of high temperature plastic flow was ob- tained,and the microstructures of the pressed samples and those before pressing were investigated with metallographic microscope.The results indicate that the strain rates of 0.001 and 0.1 s~(-1) are preferable for hot working at 960 and 1050℃,respectively.Corresponding deformation mechanisms are superplasticity and dynamic recrystallization for the former and the later,respectively.
