AbstractThis work presents the qualitative and quantitative changes in the products of isothermal transformation (reaction) in a ductile cast iron austenite after supercooling to the temperature range Ar1. The austenitizing temperature considered in this work was 900, 960 or 1020°C. The eutectoid reaction was investigated by metallographic examination at a holding temperature right below Ar11(820°C) or right below Ar12(760°C). The quantitative metallographic examination was carried out with a light microscope (LM). The initial transformation stage products were identified with a transmission electron microscope (TEM). The selected samples were studied for chemical microsegregation of manganese, silicon, phosphorus, and carbon with an X-ray microanalyser (MAR). The tested cast iron material was found to predominantly feature a eutectoid reaction in the metastable system the ratio of which was increasing with the austenitizing temperature. The austenitizing temperature was found to be conducive to the evolution kinetics of individual phases and to the graphitization kinetics of the eutectoid cementite that was formed during the contemplated reaction.

The mechanical properties of the nodular cast iron treated by troostite heat treatment were investigated, which technologies are control-cooling, adjustment at medium temperature and isothermal transformation. The fracture morphology and the microstructure were observed by scanning electronic microscope. The experimental results show that, the microstructure and mechanical properties in surface of the pieces were nearly same as that in the core after processing. Remarkable sudden change spot was not observed. The microstructure and performance with good uniformity and continuity have high stability.
