The hot deformation behavior of TiNiFe shape memory alloy was studied by isothermal compression tests.It was performed on a Gleeble-3500 thermal simulation machine at deformation temperature of 750 to 1050 ℃ and strain rate of 0.01 to 10.00 s^(-1) with maximum strain of 0.8.Deformation mechanism was investigated by the aid of true stress-true strain curves,kinetic analysis and processing map.The constitutive relationship was established in the form of Arrhenius-type hyperbolic-sine equation,and the apparent activation energy was calculated to be approximately 200 kJ·mol^(-1).The processing maps of TiNiFe alloy were appreciably influenced by true strain.
