A diffusion couple of two metals, A and B, was fashioned as shown: Diffusion of A atoms A-B alloy B Diffusion of B atoms After a 690 hour heat treatment at 1120°C the concentration of A is 1.8 wt% at the 3.2 mm position within Metal B. At what temperature (in Kelvin) must the diffusion couple need to be heated to produce this same concentration at a 2.3 mm position after 690 h? The preexponential and activation energy values for the diffusion of A in B are 1.9 x 104 m²/s and 239 kJ/mol, respectively.
[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

XB We discussed in lecture how in the early phase of a phase transformation, for example as a ß phase forms in a matrix of an a phase as shown in Fig 1.38(a), the interface between the two phases contributes to the Gibbs free energy of the ß phase. (a) In Figure 1.38(b), the Gibbs free energy curves of the ß phase are shown for a case (1) where the 3 phase is of radius r and (2) for the case where the ß phase has a radius of size. Write an expression for the difference in the Gibbs free energy of the two cases. (b) Notice the Gibbs free energy curve for the a phase on the left side of Figure 1.38(b). What can you say is different about the a phase in equilibrium with the ß phase when the ß phase is (1) of size r versus when the ß phase is (2) of size ∞.

3. A block of pure iron needs to be converted to steel. The density of iron is 7.86x10^3kg/m^3, and the atomic weight is 0.0558kg/mol. The concentration of carbon at position A is 4x10^26 at/m^3. The carbon atomic weight is 0.012kg/mol. Carbon must be diffused into the iron to convert it to steel. It is desired to have 1025 atoms of carbon per m' at point B. Position A is 1mm from position B. Assume that you have 1m^3 of iron. You heat the material uniformly to 1200°C. Do, carton = 79x10 * m/sec, Ea = 83kJ/mol, and the density of carbon is 2260kg/m^3.
