Castro Cerda, F. (author), Goulas, Constantinos (author), Hernández, Eliseo I. (author), Sanhueza, Juan P. (author), Ros-Yanez, Tanya (author), Petrov, R.H. (author)Isothermal heat treatments below the martensite start temperature are carried out in a 0.25C-1.4Mn-1.4Si-0.32Mo steel (in wt%). The microstructural observation reveals a combination of tempered lath and plate martensite, accompanied by bainite and retained austenite. The temperature variation of the austenitic carbon content under different...journal article 2023
