In this work the attempt at quantitative evaluation of the microstructure of ADI cast iron matrix has been made. The automatic analysis of the image of the microstructure of austempered spheroidal cast iron has been used for the evaluation. The treatment variant was a two-phase austenitization. First phase was carried out at a temperature t_y = 950°C and after cooling to a temperature t_y = 900°C. The isothermal process was carried out at a temperature t_pi = 300 and 400°C for 8÷64 min. Ordinary cast iron was austempered. After it the microstructure images were recorded and subjected to automatic image analysis with the use of the NIS ELEMENTS 3,0 AR software.
