I am calculating effect of grain size on mechincal properties of AISI 4140 Steel. For that purpose I am finding Hall petch contacts Ky and Sigma0. Please if anyone have this information.

Dear all
There is a new work that tries to combine both the Hall-Petch and its inverse in one model through presenting a multiscale model that enables description of both the Hall-Petch relation and its inverse in one equation without the need of prior knowledge of the grain size distribution, for more details, please see the following link:
