Compute diffusion coefficients for the interdiffusion of carbon in both (a) a-iron (BCC) and (b) y-iron (FCC) at 1000C. Assume that D0 for the interdiffusion of carbon in d-iron and in -iron are 1.1106 and 2.3105m2/s, respectively, and that Qd are 80 and 148 kJ/ mol, respectively. (a) m2/s (b) m2/s
