... . The properties of fully pearlitic steels are determined by the interlamellar spacing. A relationship similar to the Hall-Petch relationship for grain size also exists for the interlaminar spacing in pearlite, with a smaller interlaminar spacing producing a higher yield strength. Thus, strength is related...
