Constitutive model and hot workability of 2195 Al-Li alloy based on stress correction

Constitutive model and hot workability of 2195 Al-Li alloy based on stress correction

The isothermal compression tests of 2195 Al-Li alloy annealed at 400 - 490 ℃ and strain rate 0.01-10s−1 were carried out. The true stress-strain curve obtained from the experiment was modified by friction force and temperature rise effects, and the constitutive relationship was established based on...
