The Influence of Grain Size on the Mechanical Properties ...Over the range of conventional grain sizes, the values of typical mechanical properties increase with the reciprocal root of the grain size. The classic Hall-Petch equation relates the yield strength to the grain size: σy= σ0+ Kyd-1/2(1) where Kyis the Hall-Petch slope and d is the mean grain size.
