Abstract


In this work very recent results are shown that reveals the possibility of obtaining bainite by isothermal transformation at very low temperatures, of about 150°C, in high carbon high silicon steels. The microstructure thus obtained is a mixture of fine plates of bainitic ferrite (20-40 nm thickness) and thin films of carbon enriched austenite. These microstructures are very hard (600 HV) and strong (2.5 GPa).
