NaCl结构的离子晶体可以在几个非等效晶面上变形。硬度随滑移系的类型而变化。这种塑性各向异性取决于温度，二价掺杂和材料的离子性，如通过测量{110}和{100}平面上的滑移的临界分辨剪切应力所示。针对一系列NaCl型晶体，基于Peierls和位错-溶质相互作用讨论了硬化机制。塑性各向异性对分析这些相互作用有很大的帮助。
Ionic crystals of the NaCl structure can be deformed on several non-equivalent crystallographic planes. The hardness varies with the type of slip system. This plastic anisotropy depends on temperature, divalent doping and ionicity of the material as is shown by measurements of the critical resolved shear stress for slip on {110} and {100} planes. For a series of NaCl-type crystals hardening mechanisms are discussed based on Peierls and dislocation-solute interactions. The plastic anisotropy is of substantial help in the analysis of these interactions.
