A thermodynamic approach to energy storage on mechanical alloying of the Cu–Cr system

The object of this work is to estimate the increase in new surface and elastic energy during mechanical alloying of Cu–Cr powders processed by means of a SPEX mill in comparison with a regular solution model. The presence of crystalline defects increases the Gibbs free energy and the Gibbs free energy curves are moved upwards; hence the solubility limit changes.
