Interstitial Strengthening in Anisotropic Metals

Stresses, which are induced by interstitial atoms, exhibit a resistive effect with respect to mechanical loading of metallic materials, i.e., metallic materials are strengthened due to the resistive effect. Consequently, mechanical properties of metallic materials are improved due to this strengthening. This book presents an original analytical model of the interstitial strengthening in anisotropic metals. This strengthening is determined for such a model material system to correspond to real anisotropic metals with interstitial atoms. The model material system considers characteristics of these atoms, i.e., the radius R and the weight fraction wf. The analytical model is determined by different mathematical procedures, which are applied to fundamental equations of solid continuum mechanics. These different procedures result in different mathematical solutions for the interstitial stresses and strengthening.
