[5pts] Write оut the Hаll Petch equаtiоn (hint: cоnsists of 4 pаrameters.) For online submission, you can use 'S' instead of 'sigma' if desired. [2 pts] Which 2 of the parameters are material constants? [2 pts] Briefly define (in a couple of words) the other two parameters of the equation (i.e. not the material constants from part a) [2pts] In 1 sentence, what does the Hall Petch equation describe (in terms of strengthening)? [1 pt] Hall Petch strengthening can only be achieved up to a certain limit. What is this limit (provide the approximate quantitative value)? [2pts] What mechanism occurs after this limit is exceeded? [2pts] What is the typical effect of Hall Petch strengthening on ductility?
