An FCC iron-carbon alloy initially containing 0.10 wt% C is carburized at an elevated temperature and in an atmosphere in which the surface carbon concentration is maintained at 1.10 wt%. If the treatment is conducted at 1050 °C, how long should the treatment be performed to reach a 0.30 wt% of carbon concentration at a position 4.2 mm below the surface?
