Crystallization of cast iron has been shown to be a nanostructured process. Austenitic-graphite eutectic is formed from and graphite nanocrystals, free atoms. Austenitic-cementite atoms iron-carbon complexes. Primary austenite microcrystals are

In this study, it was aimed to improve the surface hardness by applying gas nitriding treatment dual-phase ductile cast iron and produce irons with a good strength-ductility combination. Thus, has been tried develop high wear resistance, strength, ductility. Ductile specimens microstructure consisting of ferrite + martensite were produced oil quenching at 70 °C after intercritical austenitizing...
