During the progress of isothermal transformation, the resistivity of austempered ductile iron vs time was recorded and then analyzed to determine the processing window X-ray diffraction, heat tinting technique, and microstructural examination were conducted to examine the suitability of this processing window in terms of microstructural chang
The impact of cutting speed and depth of cut on cutting ,
Aug 26, 2019· Parhad et al (2012) has investigated and optimized the process window for ductile iron austempered at 250 °C for varied duration of 2 h, 4 h, 6 h and 8 h respectively The optimum process window for this alloy is established in-between 4 and 5 h to 7–8 h in which structures produced are less in martensite (
Simultaneous prediction of austemperability and processing ,
Austempered Ductile Iron (ADI) is a specialty heat treated material that takes advantage of the near-net shape technology and low cost manufacturability of ductile iron castings to make a high strength, low cost, excellent abrasion-resistant material
Effect of alloying elements on austempered ductile iron ,
Austempered ductile iron castings, (or ADI castings) are ductile iron castings processed by a special heat treatment The austempering process results in ductile iron which can be used to cast complex shapes, with a greater consistency of quality, and often at less cost Click to learn more!
Austempered ductile iron (ADI) was first commercialized in the early 1970s and has since become a major industry Process [ edit ] The most notable difference between austempering and conventional quench and tempering is that it involves holding the workpiece at the quenching temperature for an extended period of time
The microstructure and mechanical properties of austempered ductile iron Authors; Authors and affiliations; K B Rundman , A processing window concept used to optimize ductility at austempering temperatures in excess of 350° C (662° F) is defined by the times needed to avoid excessive untransformed austenite volume (UAV) (the minimum time .
