Effect of cooling modes after austenitization on stabilities of microstructure and hardness of P92 steel aged at 650℃

The stabilities of microstructures and hardness of P92 steel samples austenitized at 1060℃ for 1h followed by air cooling (AC)/slow cooling (SC) and tempered at 760℃ for 2h and then aged at 650℃ for 1000h/3000h were studied by SEM-SE/BSE,EDS and multiphase separation technology (MPST). The results s...
