Compression Deformation

The hot deformation behavior of TiNiFe shape memory alloy were investigated by isothermal single-pass compression on Gleeble-3500 thermal simulator at the temperature range of 800°C to 1050°C and the strain rate range of 0.01s-1 to 10s-1. The results showed that the true stress-strain curves of TiNiFe shape memory alloy increase with decreasing deformation temperature and increasing strain rate, which indicating that the hot deformations of these conditions are dynamic recrystallization. The hot compression deformation of TiNiFe shape memory alloy can be represented by Arrhenius model. The constitutive equation of TiNiFe shape memory alloy under hot compression deformation is calculated by a linear regression analysis. The activation energy for hot deformation of the experimental steel is 202.54kJ/mol.
