...Mei Yang; Bryer Sousa; Richard Smith; Hooman Sabarou; Danielle Cote; Yu Zhong; Richard D. Sisson, Jr. X-ray diffraction (XRD) analysis with Rietveld refinement was used to determine the percentage of each microstructural constituent in AISI 5160 steel parts, which were austempered at 315°C for 1...

... and remains at this level for a relatively long time. A so-called self-regulated thermal process takes place; such a process is possible because of a significant difference between boiling and convection Biot numbers. A new quenching technology that allows for the austempering process to be performed in cold...

...Behdad Garmeh; Masoud Kasiri-Asgarani; Kamran Amini; Hamid Ghayour In this study, the effects of the austempering temperature on the microstructure and mechanical properties of carbide-free nano bainitic steel (CFB) were discussed. For the achievement of CFB 2 wt. %, silicon was added to DIN...

...Fábio Edson Mariani; Gustavo Bortoluci de Assis; Luiz Carlos Casteletti; Amadeu Lombardi Neto; George Edward Totten Austempering heat treatment of gray cast iron can significantly improve its mechanical properties. In addition, increasing its surface hardness by means of thermochemical treatments...

...J. O. Olawale; K. M. Oluwasegun Austempered ductile iron (ADI) is a group of ductile irons offering the design engineers remarkable mechanical properties. It exhibits an excellent combination of high strength, ductility, toughness, fatigue strength, and exceptional wear resistance...

...J. O. Olawale; K. M. Oluwaseguun; D. I. Ezemenaka; S. B. Adisa This paper presents the outcome of the production of austempered gray iron (AGI) using forced air cooling as the quenching medium. Samples from Class 20 gray cast iron were prepared for micrographic analysis, x-ray diffraction (XRD...

...P. O. Atanda; O. E. Olorunniwo; B. I. Imasogie The effect of process parameters on the mechanical properties of iso-thermally treated ductile irons was investigated in this study. Sets of ductile irons produced by sandwich method from a rotary furnace melt were given iso-thermal austempering...
