Abstract: | The hardening effect of Mg2+, Ca2+, Sr2+, Cd2+ and Ba2+ impurities in polycrystalline AgCl was investigated. With exception of Mg2+ the hardening effect of the impurities decreases with increasing atomic number (atomic weight). The hardening effects of Mg2+ and Ca2+ are expressively stronger than those of the three remaining impurities. Approximately linear dependence of the stress at the beginning of plastic deformation on the impurity concentration was found. Possible causes of the different hardening effects of the divalent impurities are discussed. |
