Abstract The role of interstitials on the mechanical properties of metals has become more clearly understood as the result of investigations of systems whose interstitial solute concentrations in solid solution are effectively constant over a wide temperature range (from 0 K to well into the plateau of the flow stress vs temperature diagram). These studies strongly imply that both solution hardening and dynamic strain aging are due to pinning of dislocations by interstitial solute atoms. Furthermore, the strain rate is controlled by a mechanism whose activity enthalpy is a function of the effective stress, as suggested by Yokobori.
