Thermodynamic description of the plastic work partition into stored energy and heat during deformation of polycrystalline materials

- Thermodynamic description of plastic deformation of polycrystals is presented.
- We present the stored energy as an additive component in Gibb's potential.
- This description gives a method of stored energy determination.
- Experiments show that the energy storage rate is dependent on plastic strain.
- Two components of energy storage rate are identified and determined.
