| Abstract: | In this investigation, using x-ray diffraction andelectron microscopic technique, qualitative and quantitative,analysesof the microstructures of austenite-bainite ductile cast iron subjectedto different thermal processes are made. On the basis of theseexperimenta1 results, transformation in ductile cast iron during austem-pering is discussed emphatically, At the same time, the influence ofaustenitizing temperature and time,austempering temperature and timeon the volume fraction of retained austenite and its carbon content,vickers hardness, morphology of bainite is discussed. The relationbetween volume fraction of retained austenite and its carbon contentis also involved. |
