5. 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, after 48 h, the concentration of carbon is 0.30 wt% at a position 3.5 mm below
the surface, determine the temperature at which the treatment was carried out.
