Estimate the diffusion distance of a carbon atom in fe

Reference no: EM13304883

The variation in the diffusion coefficient with temperature, over an appropriate range of temperature, can usually be approximated as follows: D= (D0)e^-(Q/(KT) where, Q = activation energy (eV/atom) and k = Boltzmann's constant (8.616*10-5 eV/atom-K) Estimate the diffusion distance of a carbon atom in Fe at 900°C and 927°C in one second and in one day. Explain the results. NOTE: At 900°C, D0 = 0.2*10-5 m2/s, Q = 0.87 eV/atom At 927°C, D0 = 2.7*10-5 m2/s, Q = 1.50 eV/atom 2)
