Thermodynamic Analysis of the Contributions from Dislocational Substructures to Deformation Processes in Single Crystals of Nickel

Аннотация

A thermodynamic analysis of deformation mechanisms is performed, based on an experimental study of dislocational substructures that form as a result of the deformation of single crystals of nickel at room temperature. It is shown that in single crystals of pure nickel, strain produces a mainly thermal effect. The most important factors responsible for the accumulation of internal energy are elastic and dislocational components.
