Nickel equivalent values were dependent on chemical composition and differences between them resulted mostly from nickel concentration in individual alloys. Chemical compositions of the alloys were selected to obtain, in raw condition, austenitic and austenitic-martensitic cast iron. Next, stability of matrix of raw castings was determined by dilatometric tests. The results made it possible to determine influence of nickel equivalent on martensite transformation start and finish temperatures.}, type={Artykuły / Articles}, title={Dilatometric Research of High-quality Nodular Cast Iron}, URL={http://journals.pan.pl/Content/106798/PDF/AFE%202_2018_29.pdf}, doi={10.24425/122521}, keywords={Alloy cast iron, austenitic cast iron, Dilatometry, Martensitic transformation, Nickel equivalent}, }
