Two-step austempering of high performance steel with nanoscale microstructure
Materials Science and Engineering: A, 2017 Abstract It is crucial to eliminate the thermally and mechanically less stable austenite blocks as much as possible if enhanced mechanical properties are demanded in high performance nanostructured bainitic steels. Step-austempering would be an efficient procedure in this regard.

Materials Science and Engineering: A, 2005 Austempered ductile cast iron (ADI) has emerged as a major engineering material in recent years because of its excellent mechanical properties. These include high strength with good ductility, good wear resistance and fatigue strength. It is therefore considered as an economical substitute for wrought or forged steel in several structural applications ...

Materials Science and Engineering: A, 2004 Abstract An investigation was carried out to examine the influence of a novel two-step austempering process on the strain-hardening behavior of austempered ductile cast iron (ADI). Strain-hardening exponent (n value) of specimens austempered by conventional single-step austempering process as well as the novel two-step process were determined over ...

Materials Science and Engineering: A, 2001 Abstract An investigation was carried out to examine the influence of a novel two-step austempering process on microstructural parameters and the abrasion wear resistance of austempered ductile cast iron (ADI). Two batches of cylindrical pin specimens were prepared from an alloyed nodular ductile cast iron and were initially austenitized at 927 °C ...

International Journal of Cast Metals Research, 2006 AbstractDue to the low wear resistance of as cast ductile iron (DI), it seemed logical to apply a recently developed two step austempering heat treatment. This process is known to enhance the mechanical properties as well as the wear properties of ductile irons.
