تأثیر ریزساختار اولیه مارتنزیتی بر فرآیند تشکیل آستنیت در فولادهای دوفازی کربن-منگنزدار

متن يادداشت

The initial microstructure of martensite in the processing of dual-phase steels has been taken into consideration due to the large sources of austenite nucleation and its filamentary distribution. In the present research, the kinetics of austenite formation in a carbon-manganese steel in different temperature ranges of the initial martensitic microstructure has been studied. For this purpose, samples of the initial heated rolled sheet were cut and subjected to austenitic treatment in optimal conditions and quenched in water to provide the initial martensitic microstructure.Then, in order to investigate the effect of temperature and holding time on the kinetics of austenite formation, the samples were in three ranges: supercritical (AC< T), intercritical (AC
