RESUMO

This work presents a study on the hardness variation in chilled nodular cast iron. A number of castings were obtained by using chills with different thickness (from O to 100 mm). The hardness variation of each casting was measured from the chilled surface (x = O) until a point far from this surface. ( x ? ? ). Based on the analysis of the resu1ts obtained mathema­tica1 equations were developed to correlate the hardness va­riation in the casting with the chill thickness
