austempered ductile iron processing window

The Processing Window for Austempering Ductile Iron

2007-5-23  A PC-controlled vacuum heat treating system was used to austemper an alloyed ductile iron with 0.77%Cu and 0.5%Ni at 400°C after austenitizing at 850°C. During the progress of isothermal transformation, the resistivity of austempered ductile iron vs. time was recorded and then analyzed to determine the processing window.

Effects of Si Content on the Microstructure and Processing ...

Abstract The effects of Si content on the variation of microstructure and processing window of austempered ductile cast iron were inves-tigated. Four different Si contents between 2.42 and 3.37 wt.% were used. The influence of silicon on the microstructure and pro-cessing window of these materials were studied. Austenitizing was performed at 900 o C for 60min and austempering temperaturewere ...
