An fcc iron-carbon alloy initially containing 0.55 wt% c is exposed to an oxygen-rich and virtually carbon-free atmosphere at 1325 k (1052 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. mis process of carbon depletion is termed decarburization.) at what position will the carborn concentration be 025 wt% after a 10-hours treatment? the value of d at 1325 k is 3.3x 10^-11 m^2/s. (you may need to use some properties of error function attached)
