600 ℃) processes on microstructure and the mechanical properties of Medium Manganese Nodular Cast Iron with 6% Mn were studied.The results show that the optimized heat treatment of Nodular Cast Iron is austenitic treated at 900 ℃ for 2 h followed by water quenching
and then tempered at 200 ℃ for 2 h before water quenching.Quenching microstructure of Nodular Cast Iron is major martensite+bainite+retained austenite+spheroidal graphite.M...
