已知多晶材料的韧脆转变、硬度、疲劳和蠕变行为在一定条件下受到多晶晶粒尺寸的影响。历史上，这些特性与材料的应力-应变行为相关。（Hall-Petch）应力-晶粒尺寸关系对于描述多晶体的完整应力-应变行为是有用的，因此，这些关系为理解这些其他性质也应该取决于晶粒尺寸的方式提供了参考。在某些情况下，特定性质的晶粒尺寸依赖性直接来自这种联系。
The ductile-brittle transition, hardness, fatigue, and creep behavior of polycrystalline materials are known to be influenced under certain conditions by the polycrystal grain size. These properties have been correlated, historically, with the material stress-strain behavior. The (Hall-Petch) stress-grain size relations are useful for describing the complete stress-strain behavior for polycrystals and, therefore, these relations provide a reference for understanding the manner in which these other properties should also depend on the grain size. In some cases, the grain size dependence of a particular property follows directly from this connection.
