Abstract The influence of a novel two-step austempering process on the microstructure and the near threshold fatigue crack growth behavior of austempered ductile cast iron (ADI) were investigated. Cylindrical tensile and compact tension (CT) specimens (for fatigue threshold tests) were prepared from an alloyed nodular ductile cast iron as per ASTM ...

A transmission electron microscope was used to study the morphology of austenite and ferrite in austempered ductile iron obtained through conventional and two-step austempering process. In this investigation, two compositions of ductile iron with carbon equivalent 4.3% (alloy 1) and 3.1% (alloy 2) were selected. Both alloys were austenitized for 60 min

The predicted processing window has been used to select temperature–time parameters for austempering of a 3·39C–2·28Si–0·48Mn–0·13Mo–0·23Cu–0·05Ni–0·034Mg (wt-%) ductile iron. Comparison of a single step austempering with two step high–low temperature regime has been carried out.

Mechanical Properties of a Medium Carbon Low Alloy Steel Processed by Two Step Austempering Process
Materials Science Forum, 2010A new bainitic steel with a combination of exceptionally high yield strength and fracture toughness has been developed. This steel has been synthesized by austempering a medium carbon low alloy steel by a novel two-step austempering process. The influence of this two-step austempering on the microstructure and the mechanical properties of this new ...
