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

Find the error function using Fick’s second law.

[Decarburization] An FCC iron-carbon alloy initially containing carbon with the concentration, C0, is exposed to anoxygen-rich and virtually carbon-free atmosphere. Under the given conditions, the carbon diffuses from the alloy andreacts at the surface with the oxygen in the atmosphere, meaning that the carbon concentration at the surface position is maintained essentially at 0 wt% C. The subproblems are independent.(1) Determine the diffusion coefficient at the temperature T given below. Use T = 1250 °C(2) When the value of D is given below, what position will the carbon concentration be Cx after a treatment for thetime, t? Use D = 1.93 × 10−10m2 /s; C0 = 0.35 wt%; Cx = 0.11 wt%; t = 12 hr
