Austempered ductile cast iron (ADI) has composite microstructures, which are martensite/retained austenite structures. ADI has very large toughness compared to other ductile cast irons. After fracture, the retained austenite near the fracture surface will be transformed to martensite. In the present study, X-ray fractography is applied to fatigue fracture surface of ADI. The fatigue tests were carried out on compact tension (CT) specimens. The volume fraction of retained austenite was quantitatively measured on and beneath fatigue fracture surfaces. The plastic strain on the fracture surface was estimated from measuring the line broadening of X-ray diffraction profiles. The depth of the plastic zone left on fracture surface was evaluated from the distributions of the volume fraction of retained austenite. The results are discussed on the basis of fracture mechanics.

Austenitic stainless steel has large toughness and high corrosion resistance compared to other alloy steels. The austenite near the fracture surface will be transformed to the martensite when it is fractured. In the present study, X-ray fractography is applied to a fatigue fracture surface of austenitic stainless steel. The fatigue tests were carried out on compact tension ( CT ) type specimens. The volume fraction of transformed martensite was quantitatively evaluated on fatigue fracture surfaces by the X-ray method. The plastic strain on the fracture surface was estimated by measuring the line broadening of X-ray diffraction profiles. The size of plastic zone left on the fatigue fracture surface was determined from the distribution of the line broadening
