RESUMO
The austempered ductile iron grade 3 was investigated as a substitute to SAE 1045 forged steel quenched &tempered in Diesel engines camshaft application. The mechanical properties for both materials were compared in laboratory tests and in the literature. The main mechanical property studied was the wear resistance. The microstructure, chemical composition was analyzed and correlated to camshaft requirements. The finishing turning machining characteristic of heated treated ADI grade 3 also was tested to verify the possibility of eliminating the grinding operation to SAE 1045 forged steel. As a conclusion of this study the ADI grade 3 complied with wear requirements when compared to forged steel and reached a finishing turning machining very close to grinding operation on forged steel. The results of this study can be used as basis to new development and production of diesel engines camshaft with austempered ductile iron
