Abstract
An attempt has been made in the current study to investigate the possibility of austenite retention in 0.5 wt pct Si steel without Al, processed through the one-step Q&P technique. The XRD and microstructural analysis confirmed austenite retention (maximum of 5.73 ± 0.16 vol pct), which showed thin film and blocky morphologies. The experimental amount of retained austenite was found to increase with the increasing quench temperature; however, it was almost independent of partitioning time. The carbon content in the retained austenite did not show any significant variation, after Q&P treatment for different time–temperature combinations. The hardness was found to be sensitive to quench temperature than the partitioning time.
