Effects of austempering time on the microstructure and properties of austempered ductile iron
Metallurgical Research & Technology, 2022The effects of austempering time on the structure and properties of high-strength austempered ductile iron were studied by using optical microscopy (OM), X-ray diffractometer (XRD) and scanning electron microscope (SEM). The results show that the matrix structure of austempered ductile iron (ADI) consists of acicular ferrite and retained austenite ...

Effect of Austempering on Plastic Behavior of Some Austempered Ductile Iron Alloys
Metallurgical and Materials Transactions A: Physical Metallurgy and Materials Science, 2011 A numerical description relating microstructure to elastic and plastic deformation behavior would make it possible to simulate the mechanical behavior of complex cast components with tailored material properties. Limited work and data, however, have been published regarding the connection between microstructure and plastic behavior of austempered ...

Effect of austempering temperature on microstructure of ausferrite in austempered ductile iron
Materials Science and Technology, 2019The effect of austempering temperature on the microstructure of ausferrite in austempered ductile iron was investigated. The results show that the grain sizes of retained austenite and acicular bainitic ferrite both become larger with the increase of austempering temperature.

Dependence of fracture toughness of austempered ductile iron on austempering temperature
Metallurgical and Materials Transactions A, 1998Ductile cast iron samples were austenitized at 927 °C and subsequently austempered for 30 minutes, 1 hour, and 2 hours at 260 °C, 288 °C, 316 °C, 343 °C, 371 °C, and 399 °C. These were subjected to a plane strain fracture toughness test. Fracture toughness was found to initially increase with austempering temperature, reach a maximum, and then decrease
