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

Abstract

• 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.
