Influence of microstructure composition on mechanical properties of austempered ductile iron

Original language description

Two austempered ductile iron (ADI) heats transformed at a temperature of 380oC in periods ranging from 2 minutes to 9 hours have been strudied in detail, with emphasis on the relation between the microstructure matrix composition and mechanical propeties. The matrix microstructure and mechanical properties of ADI are influenced especially by the dwell time (sometimes also referred to as holding time) at isothermal transformation temperature. ADI matrix called ausferrite consists primarily of acicular ferrite and stabilizued austenite. However, for short dwells some amount of martensite can occur in the matrix, which degrades the mechanical properties of ADI. The ADI with optimal combination of mechanical properties was obtained for a transformation dwell of 60 minutes, when the maximum amount of stabilized austenite in the matrix microstructure was obtained.
