The purpose of submitted work is completion pieces of knowledge about influence of structure and heat treatment contidions on static mechanical properties of austempered ductile cast iron. Owing to its excellent mechanical as well as technological properties, austempered ductile iron (ADI) belongs among very prospective structural materials. Recently it is applied in automobile and oil industry, and a considerable part of ADI production is applied also in military industry . ADI can replace steel in forged pieces, workpieces or weldments and nodular cast iron with lower level of strength properties in castings, as a rule with high economic or quality effects. The structure of ADI matrix is usually created by bainite with high strength and by stabilized austenite with high deformability. Their portion and partially also their properties are determined by transformation conditions, i.e. the temperature and the time of isothermal transformation while the austenitization conditions play only a marginal role.
