Hall - Petch Relation evaluator uses Yield Strength = Constant in Hall Petch relation+(Coefficient in Hall Petch relation/sqrt(Grain size (in mm))) to evaluate the Yield Strength, The Hall - Petch relation tells us that we could achieve strength in materials that is as high as their own theoretical strength by reducing grain size. Yield Strength is denoted by σy symbol.
