Description
Summary:Particle tracking method is given to analyze the equal channel angular extrusion （ECAE） process of NiTi alloy in non-isothermal condition. The distribution of effective strain, effective stress, the temperature, and strain rate of selected particle tracking points is analyzed respectively. The influence of friction factor is also discussed. The experimental results show that under non-isothermal condition, distribution of strain, stress, strain rate and temperature are inconsistent on relative plane. Final result indicates that distribution of effective strain on xz plane is obviously different from those of isothermal condition; load predication reveals friction factor in this mechanism made little influence on the gross of load.
