Calculate the constants in the hall-petch equation


The yield strength of mild steel with an average grain size of 0.05 mm is 20,000 psi. The yield strength of the same steel with a grain size of 0.007 mm is 40,000 psi. Determine the constants in the Hall-Petch equation, and find the predicted average grain size when the yield strength is 50,000 psi.
