The purpose of the study is to find out the relations among structure, mechanical properties, chemical composition and conditions of heat treatment of austempered ductile iron (ADI). The study is directed to obtain the best combination of strength and plastic properties of this ADI. Knowledge obtained from the study of mention characteristics creates the main basis for practical technical application of ADI. Sructure and mechanical properties of ADI are specially influenced by the conditions of heat treatment. Temperature and duration of the isothermal transformation has a special influence on the resulting structural mixture of ADI matrix and, therefore, in the same time on its mechanical properties [1]. In the study we concentrate to the structural - mechanical characteristics of ADI in dependence on the temperature of isothermal transformation in the range of 380 - 500 C.
