Problem 2. In carburizing of a piece of low carbon steel with the initial carbon centration 0.2 wt%, the carbon concentration at the surface is maintained at 1.0 wt%. The diffusivity of C in Fe is 2.98 x 10-11 m²/s, and the carburizing time is 3.68 x 104 seconds. Calculate the carbon concentration at a distance of (a) 0.5 mm and (b) 2 mm from the surface.

An FCC iron-carbon alloy initially containing 0.35 wt% C is exposed to an oxygen-rich and virtually carbon-free atmosphere at 1400 K (1127°C). Under these circumstances the carbon diffuses from the alloy and reacts at the surface with the oxygen in the atmosphere; that is, the carbon concentration at the surface position is maintained essentially at 0 wt% C. (This process of carbon depletion is termed decarburization.) At what position will the carbon concentration he 0.15 wt% after a 10-h treatment? The value of D at 1400 K is 6.9 x 10m²'s
