A sheet of BCC iron 3.4-mm thick was exposed to a carburizing atmosphere on one side and a de side at 725°C. After having reached steady state, the iron was quickly cooled to room temperature. The carbon concentrations at the two surfaces were determined to be 0.014 and 0.0060 wt%. Calculate the diffusion coefficient if the diffusion flux is 3.1 x 108kg/m²-s, given that the densities of carbon and iron are 2.25 and 7.87 g/cm³, respectively. Hint: Use Equation 5.12a-that is, for this problem Co Sch KAV to convert concentrations from weight percent carbon to kilograms of carbon per cubic meter or iron. x 10'
