Bainite transformation has yet to be utilized and even thoroughly studied in medium Mn steels.Here,we investigate the isothermal bainite transformation in a 10Mn steel at 450°C experimentally and theoretically,focusi...
The influence of carbon concentration variations on pearlite formation(20 h at 600℃)in a case-carburized steel is investigated.The resultant microstructure shows three distinct regions:carburized case,a transition re...
